摘　　要：用新一代动力学仿真软件Recurdyn建立了某军用履带车辆的简化动力学模型,将路面不平度和车辆行驶速度相结合,以路面激励的形式作用在负重轮上,利用该模型对车辆在C、D、E、F级路面上的行驶工况进行了仿真,计算出了车体的响应。其结果可为车辆的平顺性研究及车辆悬挂系统的可靠性分析提供参考。A simplified dynamic model of a tracked vehicle was created by using Recurdyn which is the latest dynamics simulation software. The roughness of road surface was combined with the run velocities of the vehicle to obtain the road excitations that are exerted to the road wheels of the vehicle. The dynamic simulations were accomplished based on the above model by letting the vehicle run on C, D, E and F grade road respectively. Responses of the vehicle were calculated. The results can be referred while studying the ride quality of the vehicle and reliability of the suspension system of the vehicle.
