Abstract: 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.
