摘要
采用多体动力学仿真软件RecurDyn的履带车辆子系统Track(HM),建立履带车辆多体动力学模型,并在MATLAB/Simulink下建立了整车动态系统仿真模型。对履带车辆在硬、软两种地面的加速过程进行动力学仿真和对比分析,着重讨论在不同滑转的条件下履带车辆的加速性能以及滑转率对加速性能的影响,为履带车辆加速性能的研究与滑转的控制提供指导。
A multi-body dynamical model of a certain tracked vehicle is created based on the multi-body dynamic software RecurDyn/Track(HM).And the system dynamical simulation model was finished in MATLAB/Simulink.The simulations of the tracked vehicle acceleration on hard and soft terrain are implemented respectively,and the results are analyzed and compared.The steering properties of tracked vehicle accelebration at vrious slip-ratio and the effects on acceleration performance are emphasized.The simulation results can provide some theoretical guidance for studying the acceleration characteristics and slip control of tracked vehicles.
