摘　　要：针对地面-履带-负重轮耦合系统激励特性的复杂问题,在不考虑履带影响的基础上,建立了履带车辆悬挂系统动力学模型,利用动力学方程实现了负重轮动位移的理论计算.建立了履带车辆的多体动力学仿真模型,对多种工况下的负重轮动位移进行模拟,并与理论计算结果作对比,分析负重轮动位移随车辆行驶速度的变化规律.研究成果为履带车辆的设计开发提供了理论参考依据,为整车道路模拟系统直接对负重轮进行位移激励加载控制提供了技术支持.For the complex problems of ground-track-wheels coupling system excitation characteristics,a dynamics model of the tracked vehicle suspension system was established leaving out the track impacts. The theoretical calculations of the road wheels dynamic displacement were realized through kinetic equation. It was then simulated under various working conditions. A multi-body dynamics simulation model was proposed. Comparing the simulation result with that of the theoretical calculations,the change regulation of the road wheels dynamic displacement with the vehicle speed was analyzed. The results provide a theoretical reference for designing and developing the tracked vehicle. A technical support for loading excitation directly on road wheels about vehicle road simulation system is provided as well.
