Restraint of negative effect on vertical vibration of wheel rim driven motor vehicle based on shake absorption principle

Aimed at the negative effect of vehicle vertical vibration caused by unsprung masses of wheel rim driven motor vehicle,a kind of scheme of mounting dynamic absorber at the steering knuckle of vehicle wheel was put forward,and the mathematical model was established.According to parameters of certain wheel rim driven motor vehicle,an optimization design was carried out on the parameters of vibration absorber.The result showed that the performance of suspension frame after optimization has been raised evidently then that before optimization.
