Lightweight commercial vehicles are not only conducive to energy conservation and emission reduction, but also bring significant economic benefits to consumers. The application of new materials is one of the effective ways to reduce the weight of automobiles. Aluminum can be used in various systems such as commercial truck body, interior and exterior trim, chassis, and trunk.
Lightweight vehicles are conducive to energy conservation and emission reduction. Studies have shown that every 10% reduction in vehicle curb weight can improve fuel efficiency by 6% and reduce carbon dioxide emissions. Low fuel consumption reduces the cost of vehicle use and brings significant economic benefits to consumers. Commercial trucks have high curb weight, high fuel consumption per 100 kilometers, and high average annual operating mileage. The effects and benefits brought by light weight are more significant.
The density of aluminum alloy material is about 27 g/cm3, which is only about 1/3 of that of steel. It is light in weight, good in lightweight effect, and has strong machinability. It can be processed into different shapes and sizes according to specific needs. It is the current lightweight for automobiles. One of the main application materials. However, the cost of aluminum alloy materials is relatively high, and the steel-aluminum connection technology is not very mature at present, which has a certain limitation on its large-scale application.
The application of new materials is one of the effective means to reduce the weight of automobiles. Due to the differences in structure and function, the application ideas of lightweight materials for the body, interior and exterior trim, frame, car box and other systems are slightly different. No matter what new material is used, lightweighting is not a simple material substitution, and the structure needs to be redesigned and fully analyzed and verified.
