Vibration tests and modal analysis method were used to recognize cause of steering wheel's idle shaking, it was found that the steering wheel's operating modal was close to engine's second order excitation frequency, which caused steering wheel's idle shaking. Five improvements were presented to relief this problem, including structural optimization, lightweight design of steering wheel, Installation of dynamic vibration absorber, matching of power train mount and reduction of engine idle speed, the effectiveness and rationality of the improvements was verified through experiments.
