摘　　要：研究履带车辆动态系统,使运动车辆缓和在路面行驶时受到的振动,使用ATV工具箱在ADAMS中建立了某履带车辆悬挂系统的动力学模型,应用多体动力学理论分析了车体、悬挂系统、负重轮、履带、路面之间的相互作用,给出了与各参数相对应的关系表达式,并描述了履带车辆运动学方程以及动力学方程。以标准梯形障碍物作为路面输入选取的各种参数进行了仿真,并将实车的车体固有频率、负重轮固有频率与计算得出的对应量进行比较,结果显示二者基本吻合,从而说明所建立的仿真模型是可信、有效的,可为设计提供参考。The dynamic model of a tracked vehicle suspension system is presented in ADAMS/ATV.The correlation of vehicle body,suspension system,road-wheel,track,and road is analyzed with multi-body dynamic theory,which is used as the parameters of ATV toolbox,kinematics equations and dynamics equations.The standard trapezoid roadblock is used as the simulation input in ADAMS,and the simulation results are compared with the natural frequencies of practical vehicle body and road wheel.The results show that the corresponding natural frequencies are almost identical and the dynamics model is verified to be reliable and effective.
