摘要 汽车方向盘作为汽车内饰件的重要部分,它的性能对于整车性能具有非常重要的影响。文章简要介绍了方向盘的一些设计要点,并通过有限元分析技术对某一方向盘进行刚度、强度、模态及疲劳寿命分析,从而辅助方向盘的设计。通过常用的有限元分析软件HyperMesh,NASTRAN和Ncode对某一方向盘进行相应有限元分析,并将分析结果与车企相关设计标准做对比,结果表明,此方向盘满足设计要求。 As an important part of automotive interior trim, the performance of steering wheel has a very important impact on the performance of the whole vehicle. This paper briefly introduces some key points of steering wheel design, and analyzes the stiffness, strength, mode and fatigue life of a steering wheel through finite element analysis technology, so as to assist the design of steering wheel. Through the commonly used finite element analysis software HyperMesh, NASTRAN and Ncode, the corresponding finite element analysis of a steering wheel is carried out, and the analysis results are compared with the relevant design standards of vehicle enterprises. The results show that the steering wheel meets the design requirements.
