Repetitive and Physical: 90 Years of Durability Testing



GM Milford Proving Ground milestone birthday today


DETROIT – In 18 months, the durability team at General Motors’ Milford Proving Ground can put a vehicle through an entire lifecycle. Durability tests are long, repetitive and physically demanding.

“In 90 years, what hasn’t changed is that durability testing is physical,” said Stephen Jenkins, director, Global Proving Ground Operations, Test Labs and Vehicle Material Engineering. “We can mathematically calculate how well a part should hold up under certain conditions, but it isn’t until we get a driver in the product and test over and over again that we can be sure.
Here are some of the benchmarks a vehicle must endure before the Milford durability team will release it for production.

·         100,000 miles of customer use – the team drives a test vehicle up to 25,000 miles, though it is in such extreme conditions that it represents 100,000 miles of customer use
·         Extreme tests – Belgian Block Loop, pothole drives, chatter bumps, twist ditches, speed bumps and more are driven for entire days testing various parts of the vehicle
·         Humidity chambers - Built in the late 1960s with new ones added in the 1980s, every car is soaked in humidity chambers. On numerous occasions cars will go in these corrosion booths for hours at a time and endure high temperatures and humidity      

“We are always pushing ourselves to test even the smallest part of a vehicle to ensure that the entire product from the engine down to the screws and bolts are tough enough to handle the driving our customers need,” Jenkins said.

General Motors Co. (NYSE:GM, TSX: GMM) and its partners produce vehicles in 30 countries, and the company has leadership positions in the world's largest and fastest-growing automotive markets. GM, its subsidiaries and joint venture entities sell vehicles under the Chevrolet, Cadillac, Baojun, Buick, GMC, Holden, Jiefang, Opel, Vauxhall and Wuling brands.

Chevrolet’s Crash Course on Avoiding Collisions



Advanced technologies can help customers in common crash situations

 
DETROIT – Even the best, most defensive drivers can end up in an unexpected crash. Chevrolet’s 2015 lineup provides key features that help protect drivers and passengers before, during or after a crash, but the focus is on new technologies aimed at helping avoid the crash in the first place. 
According to a 2012 National Highway Traffic Safety Administration report, more than one in four police-reported vehicle crashes each year are rear-end collisions between a driver and the vehicle they are following, Nearly one in 10 happen during lane changes made at the wrong time.
Chevrolet is using cameras, radar and ultrasonic sensor technology to help drivers avoid these rear-end collisions and blind spot-caused sideswipes, as well as parking lot fender benders and more.
“The best kind of safety protection we can offer are customer-focused features that help drivers avoid the crash altogether, and which are kept turned on for every trip”, said Raymond J. Kiefer, General Motors Active Safety Technical Fellow.
Kiefer and his team developed the patented “Safety Alert Seat” feature to help hearing-impaired drivers and persuade drivers to leave features turned on.
Like a Smart phone, a driver can select vibrating rather than beeping alerts that intuitively “tap” them on the left, right, or both sides of the seat bottom to help direct their attention to a possible crash situation detected by the vehicle sensors. The Safety Alert Seat is available on Silverado, Tahoe, and Suburban.

Chevrolet’s crash avoidance technologies are designed to help drivers in many everyday situations, though none substitutes for careful, distraction-free driving, use of seat belts and child seats when appropriate, obeying traffic laws and driving sober and unimpaired.
Here are a few Chevrolet crash avoidance technologies: 

Rear Vision Camera, when backing, displays the scene behind that may be unseen by the driver or in mirrors.  Uses a rear camera. Available across the Chevrolet lineup. 

Rear Cross Traffic Alert lets you know if a car is approaching from the side when backing, such as when parked between two large vehicles. Uses two rear corner radars. Available on 2015 Cruze, Impala, SS, Traverse, Tahoe and Suburban.

Side Blind Zone Alert, alerts the driver if a vehicle is in the left or right side blind spot – before a possible lane change. Uses two rear corner radars. Available on Cruze, Impala, SS, Traverse, Tahoe and Suburban.

Forward Collision Alert, may “see” a crash situation before you do, and can alert when a driver when a crash into a vehicle you are following is imminent. Uses front camera and/or radar. Available on 2015 Volt, Malibu, Impala, Equinox, SS, Traverse, Colorado, Silverado, Tahoe, Suburban.

Other Chevrolet crash-avoidance features include Front Automatic Braking, Adaptive Cruise Control, and Lane Departure Warning.

Front Automatic Braking automatically applies the brake when the system may see a crash situation ahead before you do, and can be thought of us a “backup” or “Plan B” if you do not respond quickly to Forward Collision Alert warnings, or if a rear-end crash situation quickly unfolds. At lower speeds, the feature may even help avoid the crash, while at higher speeds, it can reduce crash severity and injury. Uses front radar.

Adaptive Cruise Control works like regular cruise control until you are following a vehicle ahead, when it automatically accelerates and brakes (up to moderate levels) to help follow at a driver-selected cruise speed and following gap while you steer and pay attention to the road. Uses front radar.

Lane Departure Warning can alert a driver who drifts out of detected lane lines unintentionally or without a turn signal, when traveling faster than 35 MPH, which can sometimes happen to distracted or tired drivers. Uses front camera.

The focus on driver and passenger safety is a pillar of the Chevrolet. Examples of safety leadership include:
  • Chevrolet has more vehicles with a 5-star Overall Vehicle Score from the federal government than Toyota or Ford. Models include Sonic, Volt, Camaro Coupe, Malibu, Impala, Traverse and the Silverado 1500 Crew Cab).
  • The 2014 Chevrolet Equinox and Malibu received Insurance Institute for Highway Safety 2014 Top Safety Pick + ratings – the highest conferred – on models with available forward collision alert. Equinox and its GMC sibling, the Terrain, were the only compact SUVs of nine tested to earn this rating.
  • The 2014 Spark is the only mini car named an IIHS Top Safety Pick.

Founded in 1911 in Detroit, Chevrolet is now one of the world’s largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.

Silverado HD Strong Arms the Competition



Frame twist test shows importance of strong materials in big job pickups
 


DETROIT – How tough are heavy-duty trucks? A recent frame-twisting test found that the use of roll-formed steel in its bed allowed the tailgate of the 2015 Silverado 2500HD pickup to be lowered on uneven terrain while greater twisting of one competitor's frame kept its tailgate from being lowered.
AMCI Testing, a third-party research firm hired by Chevrolet, recently subjected the 2015 Silverado 2500HD and a Ford F-250 Super Duty to a rigorous frame twist test, in which the truck was driven onto two staggered ramps, where the wheels on one side of the truck hit the ramp before the other, placing a large amount of torque on the frame. Measurements were then taken for the distance of displacement of the cab body and the bed, determining the amount of twist to which the frame is subjected.
AMCI found that during the test, the Silverado HD’s frame allowed 0.26 inches of twist, while the F-250 Super Duty allowed 0.94 inches of twist, 262 percent more than the Silverado. The twist was so great on the Ford that when under stress, the tailgate could not able to be lowered, while the Silverado’s available EZ-Lift and Lower Tailgate operated normally. You can see the test here. 
“The use of high-strength steel in the Silverado HD is what allows the Silverado to handle even the toughest of jobs,” said Jeff Luke, General Motors’ executive chief engineer for full-size trucks. “Paired with a fully boxed frame, high-strength steel is what makes the Silverado come from the family of the most dependable, longest-lasting full-size pickups on the road.”
Roll-formed steel in the Silverado HD vs. the stamped steel bed of most competitors involves using a higher-grade steel that’s stronger, lighter and more durable. The fully boxed frame provides a rigid foundation.   
The Silverado’s body is also constructed using similar high-strength steel. Approximately 67 percent of the cab is constructed with high-strength and ultra-high-strength steels. They’re used in the A-pillars, B-pillars, rockers and roof rails, as well strategic sections on the interior structure.
Ultra-high-strength steel is used in areas of the rocker panels and underbody to help improve crash performance. The Silverado uses more high-strength and ultrahigh-strength steel than any competitor’s full-size pickup truck, according to market research firm Ducker Worldwide.
Founded in 1911 in Detroit, Chevrolet is now one of the world’s largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year.

The Case for Roll-Out Cargo Beds


One of the challenges to maximizing cargo space in a truck or van is that sometimes there is a need to store product, tools, or gear in areas that are difficult to reach. This negatively impacts productivity by increasing loading and unloading times and puts workers at greater risk of musculo-skeletal disorders.


A roll-out cargo bed, which operates like a large flat drawer on the cargo floor in a van or truck bed, could solve this problem and protect the worker’s health, making the most of the cargo space, without having to enter the truck bed or van cargo area, for quicker and safer loading and unloading.

The business case for roll out cargo bed systems is based on increased productivity and reduced injuries. Making tools and equipment easier to access not only saves time and energy for workers, but also protects them from getting hurt when they need to get to hard-to-reach items.

Five Ways Chevrolet Builds Strength into Silverado



From strong frames to advanced small-block engines, Chevy trucks are built to last 



DETROIT – Chevrolet Silverado is from the family of the most dependable, longest-lasting full-size pickups on the road. That durability is derived from strength   in everything from the foundation on which the truck is built to the engine that pulls it down the road.

“Every element in the Silverado is designed to get the job done for our customers, year after year after year,” said Sandor Piszar, director of Chevrolet Truck Marketing. “We’ve engineered new technologies to take Silverado to higher levels of capability and efficiency, but never at the expense of the trust owners have put in it.”

The 2015 Silverado’s strength can be measured through five core elements:

1. Fully Boxed Frame
Silverado’s fully boxed frame – including main rails and major cross members formed from high-strength steel – provides a rigid base for maximum hauling capability, excellent crashworthiness and the longevity truck customers demand.

The frame comprises three sections: front bay, mid bay and rear bay. The front frame bay uses hydroformed side rails for optimal strength and lower weight. Pioneered by General Motors for full-size trucks 15 years ago, the process uses highly pressurized fluid to shape the frame rails, making them stronger and lighter than comparable welded multi-piece components.

The side rails of the frame’s middle bay are constructed of two pieces of high-strength steel welded to form the sturdy box design. The front bay’s hydroformed rails slip inside the boxed sections of the middle bay 9.4 inches (240 mm), creating a bend-resistant rigid structure, while the rear-bay boxed rail sections are joined to the middle bay with an overlapping, shingle-type construction. A frame-integrated hitch enables maximum trailering capability right from the factory.

Engineers validated the frame’s strength in the lab and in the field. In the lab, Silverado prototypes were mounted by their wheel hubs on a simulator that shook and twisted them with extreme intensity. Outdoors, they were driven over a variety of rough surfaces and swells – including torturous “truck blocks” – inducing natural frequencies and real-world driving conditions that don’t occur in the lab.

2. High-Strength-Steel-Reinforced Body Structure
Silverado’s body structure, which features advanced, high-strength steels, complements the fully boxed frame to enhance its strength and safety performance. High-strength steel contributes to Silverado being the only full-size pickup to earn a 5-Star overall rating in government crash tests.

Approximately 67 percent of the cab is constructed with high-strength and ultra-high-strength steels. They’re used in the A-pillars, B-pillars, rockers and roof rails, as well strategic sections on the interior structure. Ultra-high-strength steel is used in areas of the rocker panels and underbody to help improve crash performance.

High-strength steel can be up to 30 percent lighter than carbon steel with the same strength, offering significant mass savings at a lower cost than aluminum, which helps keep down the overall vehicle cost. Lower weight translates to greater efficiency and capability for truck owners.

3. Tough Cargo Box and Tailgate
Silverado has the industry’s most innovative cargo box and supporting features, including two-tier loading, standard integrated cargo tie-downs, available adjustable tie-down hooks, ergonomically shaped handholds built into box rail protectors and the CornerStep, which enables easier climbing access to the box and to retrieve items from it.

The Silverado’s cargo box floor is made of roll-formed steel that’s stronger and lighter than conventional stamped steel. Lower weight helps control the truck’s overall mass, which enhances efficiency, while the stronger steel bolsters the box’s durability.

The roll-forming process takes a long strip of steel and passes it through a set of rolls, each performing part of the desired bend until the final shape is reached. The process allows the use of higher-strength steel, because the metal does not need to be shaped as much as it does during a conventional stamping process. The process also generates less scrap.

Additional elements that enhances the cargo box’s strength include:
·         Spray-on stone protection on the outside of the box offers improved paint protection and corrosion resistance  
·         Available, factory spray-on bedliner helps protect the bed when hauling cargo
·         Box rail protectors are incorporated along the top of the box sides and across the top of the tailgate to protect those areas from damage.

The Silverado’s tailgate was subjected to a load bearing test during development to help ensure it is strong enough for just about anything customers will throw at – or on – it. The test included dropping a 400-pound (181 kg) load in a concentrated area on the tailgate to test the strength and durability of the tailgate panel, torque rods and cables.

The available EZ Lift-and-Lower tailgate eases cargo loading. An internal torsion bar reduces the effort to raise and lower it the tailgate, while a rotary damper allows for a controlled and more gradual lowering motion during opening.

4. Advanced Small-Block Engines
With the ability to operate on four cylinders during light load driving, Silverado’s 5.3L EcoTec V-8 offers the best fuel economy estimates – up to 23 mpg highway – of any truck V-8. Yet this same engine builds on more than 100 million engines’ worth of experience. The Chevrolet’s small-block has been the heart of Chevy trucks for 60 years – and the engine on which generations of truck customers have depended.

The 2015 Silverado 1500 lineup features a trio of fifth-generation small-blocks:
  • A 4.3L V-6 SAE-certified at 285 horsepower (212 kW) and 305 lb-ft of torque (413 Nm) – the most torque of any standard V-6
·         A 5.3L V-8 SAE-certified at 355 horsepower (250 kW) and 383 lb-ft of torque (519 Nm). With EPA-estimated fuel economy of 23 mpg highway (2WD), it offers the best fuel economy of any V-8 pickup, and beats the fuel economy estimates of the Ford EcoBoost V-6
·         A new 6.2L V-8 offers the most powerful engine in any light-duty pickup truck, with SAE-certified 420 horsepower (313 kW) and 460 lb-ft of torque (623 Nm).

Each engine features direct injection, Active Fuel Management (cylinder deactivation) and variable valve timing for power, torque and efficiency across a broad range of operating conditions. Additionally, the proven cam-in-block architecture of the small-block family is less complex and more compact than overhead-cam designs, while providing excellent low-rpm torque – the pulling power truck customers need when starting off with a loaded cargo box or trailer. 

5. Long-Lasting Duralife™ Brake Rotors
All Silverado 1500 models have standard four-wheel disc brakes with new Duralife™ brake rotors that offer up to double the service life. They enhance braking performance, too, thanks to a GM-exclusive process that protects against rust that, over time, can lead to steering wheel shudder.

The process involves super-heating the rotors to more than 1,000 degrees F (560 C) for an entire day in a special oven, where the nitrogen-rich atmosphere promotes nitrogen atoms to bond to the rotors’ surfaces, hardening and strengthening them.

The large, vented front brake rotors measure 13 inches in diameter and are complemented by 13.6-inch rear rotors, which enable confident, sure-footed braking performance even with a fully loaded cargo box or when trailering. An engine-driven vacuum pump enhances braking capability, too, through greater brake system boost.

Silverado also features Auto Grade Braking, which uses the engine and transmission controls to slow the vehicle on a long downgrade, helping maintain vehicle speed and reducing the need for the driver to use the brakes.

Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year.
