摘　　要：针对方向机传动齿轮接触应力问题,构建一种基于ABAQUS软件的方向机传动机构的模型。以某自行高炮方向机为例分析其有限元模型,通过施加边界约束和载荷,得到方向机传动齿轮接触应力及变形,采用有限元法对传动齿轮的变形和接触应力进行了数值仿真,并与赫兹理论估算的传动齿轮接触应力进行比较。仿真结果证明:该方法有效,有限元方法与赫兹接触理论的计算结果基本一致,2种方法计算结果相差分别为5.19%和1.64%。To solve the problem of contact stress of transmission on traversing mechanism, the traversing mechanism transmission gear model was built by ABAQUS. Takes certain-type self-propelled gun traversing mechanism as example to analyze finite element model, the boundary constraints were built and loads were applied. Then acquire traversing mechanism transmission gear contact stress and deformation. Use finite element method to carry put numerical simulation on gear deformation and contact stress. The contact stress of transmission gear was calculated by Hertz theory. Through comparison of the two results, the simulation result show that the method is valid, and the calculation results are similar. The difference of two method calculation results is 5.19% and 1.64%.
