摘　　要：文章结合模态分析理论,通过有限元分析方法对电动助力转向管柱进行模态分析,针对转向管柱在水平方向不满足设计要求的问题对重要散件提出优化方案,并再次进行有限元分析,基于理论分析可行的基础上,制作优化样件并进行台架测试,最终测试结果显示优化措施改善明显,该优化分析方法可为今后转向管柱的固有频率功能开发提供借鉴。Based on the theory of model analysis,the Finite Element Analysis method is used to conduct model analysis on the Column Electric Powered Steering System,and optimized plan for important parts for the problem that the steering column cannot meet the design requirements in the horizontal direction is proposed.Based on the feasibility of theoretical analysis,an optimized sample is made and tested on the bench.The final test results show that the optimization measures are improved significantly.This optimization analysis method provides a useful reference for the development of the natural frequency function of the steering column in the future.
