摘　　要：为了提高履带推土机负重轮的使用寿命,采用多体动力学仿真软件RecurDyn,针对履带推土机推土转向作业工况进行运动学与动力学仿真分析,研究履带推土机行走系统在推土转向作业工况负重轮的受力状况,得出制动侧与驱动侧行走系统中各负重轮所受载荷分布规律,转向中心的位置以及在此工况下容易发生啃轨、漏油的负重轮位置,主要采用对调负重轮位置的方法解决。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 improve the service life of the road wheel of crawler bulldozer,multi body dynamics software RecurDyn was used; it conducted the kinematics and dynamics simulation analysis aiming at the bulldozing steering working condition of crawler bulldozer. It studied the stress condition of the road wheel of crawler bulldozer walking system in bulldozing steering working condition. It was identified that the brake side and drive side travel system load distribution regularity of road wheel,turning centre location and the location of road wheel that was easy to chew rail and leak oil at such conditions. Then swapping the position of load wheel could be adopted to solve those problems. The virtual prototype technology used 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.
