SIMULATION AND ANALYSIS OF INFLUENTIAL FACTORS OF RIDE FOR HIGH-SPEED TRACKED VEHICLES

Simulation plays an important role on the systematic research of tracked vehicle dynamics. A multibody dynamic ride model of the tracked vehicle was established and was proved to be valid. On the basis of this model, the factors influcencing ride quality were analyzed.These factors include road roughness,speed and structual parameters. Influence of terrain roughness on the ride was given by traveling on good terrain, medium and rougt terrains. Influence of velocity on the ride was shown by traveling in different speeed. Analysis of influence of damping on ride quality provides some guidance to semi-active control of tracked vehicles. The results are beneficial to strengthening the roles of simulation in the research and to improving the performance of tracked vehicles.
