汽车转向系统中间轴节叉开裂分析及优化

Analysis and Optimization of Yoke Crack of Intermediate Shaft of Automotive Steering System

以某SUV车型为研究对象,利用UG/FEA建立有限元模型,结合传统与雨流法疲劳分析,材料分析,对汽车转向系统中间轴的节叉开裂问题进行分析,找到根本原因,提出改善措施。

In this paper,an SUV model as the research object,using UG/FEA finite element model,combined with traditional and rain flow method fatigue analysis,material analysis;studies the Yoke crake issue of I-Shaft in vehicle steering system,find the root cause and solution.
