CAE Analysis and Optimization Design of Wheel Rim Based on Pendulum Impact Test

Zhang Anxia Hu Depeng

Abstract:The pendulum impact method transforms the height difference potential energy into the pendulum kinetic energy, which is easier to achieve the target speed and has good repeatability. In this paper, the impact resistance of wheel rim is studied based on the pendulum impact test, and the structure of wheel rim is optimized by CAE analysis to improve the impact resistance of wheel rim.

Key words:Pendulum Impact, CAE analysis, Impact resistance, Wheel rim

1 前言

汽车车轮是介于轮胎和车桥之间承受负荷的旋转件,是汽车行驶系统中重要的安全部件,起着承载、转向、驱动、制动等作用[1],因此研究轮辋的安全性具有重要意义。(剩余3221字)
