单片冲压式汽车下控制臂轻量化优化设计

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

摘要:

以某国产车型的焊接型下控制臂为结构轻量化设计对象，综合运用多种优化方法，设计出一款全新的单片冲压型下控制臂.该单片冲压型下控制臂在满足原焊接型下控制臂所需的各项性能的基础上，较原控制臂质量减轻33.3%，轻量化效果显著.

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.
