Modal Analysis of Automotive Steering System Based on Finite Element Method

摘要：

　　In order to understand the vibration characteristics of the steering system and provide suggestions for improvement,a model of the steering system was created based on finite element method (FEM).Also,the modal analysis of the steering system was presented,and the first twenty step modes were calculated and analyzed.The steering system was also evaluated from the resonance point of view.The result shows that the frequency of the first step mode is 31.578 Hz which is higher than the exciting frequency of the engine; also,the road roughness excitation frequency has a minor influence on steering wheel vibration.
