Flexible, energy-absorbing components that attach parts of a vehicles drive train to the chassis

During a crash event, flexible, energy-absorbing components are attached to parts of a vehicles drive train to control kinetic energy and to protect the driver and passengers. These parts are either manufactured to be factory-installed or are designed as optional parts. Depending on the structure, these parts may be made of composites, metal or wood. They are also used to enhance the absorption of crushing energy. They are usually based on a combination of strength and stiffness.

These structures have been used in small volume production vehicles, but are increasingly being used in high volume production vehicles such as trucks and SUVs. Their benefits include less space, greater flexibility and affordability. They can be connected by welding or adhesive bonding. They are often made of aluminum alloys or multi-materials. They may also include a climate control system, which regulates the temperature in the vehicle's rear seat. They also have digital displays which convey information to the driver. These include displays that provide information on the vehicle's average speed, fuel economy and distance traveled. The displays may also be analog.

In addition, these structures have been used for racing. In some cases, the structure is shaped like a fish mouth. Occasionally, they are covered in metal or glass to minimize light transmission. In other cases, they are used for aesthetic reasons. They may also be made of a combination of wood, composite, leather and metal. They are usually used for vehicles in which the engine is located in the front.

These structures are characterized by a network of rigid joints. The components of this structure include side pillars, the upper pavilion and the door-opening panels. The structure is typically made of a molded steel sheet. They are spot-welded and then fitted with the engine and other structural components. In addition, they are often made of aluminum closures.

China Turning Parts For Automotive Manufacturers, these structures are designed to absorb energy through progressive deformation. They are usually designed with a primary crush zone and a secondary crush zone. The primary crush zone is located in the fore section of the powertrain compartment. Its size is generally between 150 mm and 500 mm. It is the main energy-absorbing element of a vehicle's frontal structure. During a crash, elastic waves and plastic flow propagate in the structure. In addition, the shape of the structure determines its capacity to absorb energy. This is because the second moment of area of a structural shape is a property of the shape. This second moment of area is inversely proportional to the Young's modulus of the material. It is therefore important to consider the material contribution to the structure's strength.
