履带车辆路面激励响应的简化计算

摘要

为了快速计算履带车辆在路面不平度激励下的动力学响应，基于合理假设采用理论力学方法建立了某履带车辆的简化动力学模型，用ADAMS软件建立了同种工况下的履带车辆动力学模型，并把两种模型的求解结果进行了对比，验证了简化模型的合理性．研究结果为基于简化模型的动力学方程对车辆悬挂系统进行优化和逆动力学分析奠定了基础．%In order to quickly compute the dynamic response of a tracked vehicle stimulated by the road roughness, a simplified dynamic model of the tracked vehicle is created based on the theoretical mechanics principle and by neglecting some secondary factors. Meanwhile, a dynamic model of the tracked vehicle is built through ADAMS. The comparison between the results of the two models verifies the reasonableness of the simplified model. The results provide a foundation for the optimization design of the suspension system of a tracked vehicle and the inverse dynamics analysis based on the simplified dynamic model.
