摘　　要：采用多体动力学仿真软件Recur Dyn对履带推土机行走系统推土转向作业工况进行运动学与动力学仿真研究.建立了与实际工况相同的仿真模型,对驱动轮力矩、张紧弹簧和托链轮所受载荷进行分析,得出各自所受载荷规律.所采用的虚拟样机技术,可作为履带式工程机械仿真研究的方法,仿真结果可作为履带推土机设计与优化的参考依据.In order to study stress condition of various parts of walking system of crawler bulldozer when bulldozer is bulldozing as well as steering, this article uses the Multi Flexible-Body Dynamics simulation software RecurDyn, it is created the simulation model that is the same as practical condition. The driving wheel torque, tension spring and carrying wheel load are analyzed and studied. Then it concluded that the law of load above parts. The virtual prototype technology can be applied to simulation research of tracked engineering machinery. The simulation results can be used as reference of design and optimization of crawler bulldozer.
