Vehicle steering wheel’s idle shaking has negative effect on driving comfort. The cause of steering wheel’s idle shaking was recognized through vibration test and modal analysis method. It was found that steering system’s operational modal was close to the 2nd order excitation frequency of the engine, and steering wheel resonated. To relief this problem, five improvements were presented, including structure reinforcement, lightweight design of steering wheel, installing of dynamic vibration absorber, matching of power train mounts and increase of engine idle speed. The effectiveness of each improvement was proved through experiments.
