At present, the automobile industry is facing multiple problems such as the gradual improvement of emission standards, the continued high consumption of gasoline for residents, and the continuous rise in the manufacturing cost of new energy vehicles. Lightweight has obvious advantages in the face of the above problems, which is the general trend of the automobile industry, and many countries are also Lightweight is advocated in this policy. Compared with traditional fuel vehicles, new energy vehicle companies are more motivated to implement lightweighting, because vehicle weight reduction can reduce battery costs under the same conditions, and new energy vehicle companies will directly benefit.
At present, there are three main ways to reduce the weight of automobiles. One is the lightweighting of automotive materials, the second is the lightweighting of the structure, and the third is the lightweighting of the manufacturing process. Most of the car companies focus on the lightweighting of materials in the process of lightweighting. The current advantage of aluminum alloys in lightweight materials is the most obvious. We estimate that the automotive aluminum alloy market space is expected to reach 177.9 billion yuan by 2025. Structural lightweighting can be divided into size optimization, shape optimization and topology optimization from simple to difficult, among which topology optimization has the best effect. The lightweight manufacturing process mainly includes laser welding process, hydroforming process, hot stamping process and integrated die-casting process, among which the integrated die-casting process is currently the most popular.
The common lightweight directions of car companies are as follows: (1) Use aluminum alloy materials on automotive chassis systems, power systems, body structures, battery boxes and other components; (2) Use plastics instead of steel on automotive interior and exterior trim parts However, due to the low proportion of interior and exterior decoration in the weight of the vehicle, it is insufficient for car companies; (3) The integrated die-casting process is used on the body structure and battery box. Both the end and the manufacturing end have high barriers.
