Dynamic Simulation and Experimental Analysis on Ride Comfort Performance of Tracked Vehicle

A comprehensive nonlinear vehicle model of a tracked vehicle suspension is established by using multi-body dynamics software Recurdyn, which is used to be simulated ride comfort dynamic response. In the paper, the multi-body model dynamics vibration characters of vehicle suspension is simulated, which is accomplished by testing the model on the different roads (such as level-D,E&F Road) by different vehicle riding speed. The influence factors about ride comfort are found by the stimulation, which are the road level,the velocity of the vehicle and other parameters of the suspension system. The experiment about the vehicle ride comfort performance proves that using the multi-body model simulation in the paper could be helpful to select appropriate suspension system parameters in the structure and performance design about tracked vehicle suspension, which could give theory bases about suspension active controlling strategy of the suspension.
