With the continuous increase of the total number of cars, the contradiction between automobiles and energy and environmental protection has become a prominent problem that restricts the sustainable development of the automobile industry. Facing the arrival of the low-carbon era and the tremendous pressure of energy conservation and emission reduction, vehicle lightweighting is the most effective and realistic way to solve this problem.
one. Thereby promoting the application and development of new materials and new processes in the automotive industry. Among them, the most striking is the application and development of aluminum alloy in the lightweight of automobiles. This paper starts with the lightweight design of the car seat from the aspects of lightweight lightweight seat frame structure, structural optimization design and forming process analysis.
As the total number of vehicles and new additions continue to increase, vehicle fuel consumption and emissions of carbon dioxide, harmful gases and particulates from automobiles are also increasing rapidly. Today, with the shortage of energy and the deterioration of environmental benefits, this contradiction has become a prominent problem that restricts the sustainable development of the automobile industry. Faced with the enormous pressure of energy crisis and low-carbon environmental protection, one of the most effective and realistic methods to solve this contradiction is also the trend of the development of the world's automobile industry, which is to achieve the lightweight of automobiles.
1. Automotive lightweight concept Lightweight of Automobile is to reduce the weight of the car under the premise of ensuring the performance of the car, such as strength, rigidity and safety, thereby improving the car's power performance, fuel economy, and Reduce exhaust gas pollution. Lightweight vehicles are not just about reducing the weight of cars. They also include many new theories, new materials, and new processes.
