Lightweight Design of Optimization of a Single Piece of Stamping Control Arm of Vehicle

Abstract:

In this paper, the welding control arm of a domestic vehicle is designed for lightweight, using a variety of optimization methods to design a new single stamping lower control arm. The new control arm not only meets the various functions of the control arm of the original welding type, but also has a weight loss of 33.3% compared with the original control arm, achieving the purpose of lightweight.

Key words:lightweight; lower control arm; structure optimization; fatigue analysis
