摘　　要：湿地推土机的工作路面是沼泽地面,终传动系统是湿地推土机的重要组成部分,能够将发动机输出的转速和力矩进行减速增矩,将动力传递到行走系统.由于结构形式复杂,如果采用传统的理论方法计算终传动系统各零部件受力形式,计算过程十分复杂.利用多体系统动力学理论建立湿地推土机动力学模型,对直线推土和满载转向两个工况中终传动系统的重要零部件——一级齿轮、二级齿轮、半轴以及大齿圈轮毂进行受力分析,为半轴与大齿圈轮毂的改进提供参考.Wetland crawler bulldozer works in swampland.Final drive system as an important part of wetland crawler bulldozer,passes the speed and moment to the walking system.The forces between parts are not easy to simulate by theoretical calculation due to the complex structures.However,they can be simulated easily by dynamic theory.The dynamic model of wetland crawler bulldozer was built.The forces in pushing soil straightly and turning fully loaded are simulated by dynamic theory included single reduction gear,double reduction gear,half axis and large gear ring wheel hub,which provide some preferences for the design of wetland crawler bulldozer.
