摘　　要：以采煤机牵引部为研究对象,在三维软件中建立其实体模型,采用静力学与动力学仿真相结合的方法模拟齿销啮合运动特性和力学状态。通过静力学仿真得出行走轮单齿在不同啮合位置时的应力状态,找出更符合实际的最大应力位置,分析了造成轮齿折断的不同原因。构建了齿销啮合的动力学仿真模型,得到不同牵引速度下啮合力的变化规律,为采煤机行走机构的进一步设计优化提供了理论参考。Taking the walking mechanism of the shearer as the research object, established its model in the three-dimensional software, and simulated the motion characteristic and mechanical state of the teeth-pin meshing by the method of static and dynamic simulation. Through the static simulation the stress states of the single tooth in the different meshing position were obtained,the maximum stress position which is more conformable to reality was found and the different reasons for the tooth breakage were analyzed. The dynamic simulation model of the teeth-pin meshing was set up and the variation regularity of the meshing force under different traction speeds were obtained,which provides a theoretical reference for the further optimization design of the shearer′s walking mechanism.
