摘    要:软路面行驶时,履带式试验车的行驶性能主要体现在履带板在软路面上的沉陷量、履带的打滑率以及试验车主轴的扭矩等几个方面。介绍ADAMS/ATV中软路面模型的计算方法,然后在完成履带式试验车机械设计的基础上,建立ADAMS/ATV虚拟样机模型,对履带式试验车在软地面条件下的行驶性能进行仿真分析。通过对仿真结果的分析和计算可知履带板的沉陷量为0.045 m到0.055 m,试验车的打滑率为5.37%,验证试验车设计的合理性。通过对履带式试验车驱动轮主轴扭矩的仿真分析,得到稳定状态下主轴平均扭矩为126.5 N·m,启动扭矩为239 N·m,为试验车动力参数的确定提供理论依据。

Abstract: The walking performance of tracked test vehicle tracking on soft road mainly includes the penetration of belts, the slip rate, the main torque of the shaft. The calculation method of soft road model in ADAMS/ATV was introduced. The virtual prototype model was built on the platform of ADAMS/ATV, based on the completion of mechanical design of tracked test vehicle. The walking performance of tracked test vehicle tracking on soft road was simulated. The penetration of belts range from 0.045 m to 0.055 m, and the slip rate is approximately 5.37%.The design rationality of tracked test vehicle was verified. The torque of main shaft is 126.5 N·m and the start torque is 239 N·m, providing theoretical basis for the determination of the dynamic parameters of the test vehicle.
