In the process of automobile development, in order to reduce the weight of the whole vehicle and maximize the performance of limited materials, lightweight and topology optimization are often involved. While meeting the development and design goals of automobiles, a suitable lightweight guidance scheme for parts is proposed, which is conducive to saving automobile manufacturing costs and reducing energy consumption. In the early stage of the development of a certain car model, a car company has a stricter definition of the vehicle curb weight, and puts forward higher requirements for the lightweight design of each part. The lower control arm is an important part of the automobile chassis. Through the topology optimization method, the lower control arm is used as a design variable, and the finite element software is used for topology simulation. Structural design scheme.
