摘　　要：基于有限元软件ANSYS建立了双圆弧齿轮静态和动态接触的计算模型,讨论了在真实转动情况下计算齿轮接触应力、应变应该注意的一些事项。介绍了静态接触模型中约束和载荷的处理方法,以及动态模型中施加相当于转矩的跟随载荷的具体方法,讨论了刚体在静态和动态模型中的作用和影响。通过对静态和动态模型计算结果的比较,说明了动态模型方法是可行的。Static and dynamic contact calculation model for double arced gear was established based on finite element software ANSYS, and a number of items that ought to be paid attention to on the calculation of contact stress and strain of gear under real operation condition were discussed. The treatment method on restraint and loading in the static contact model and the concrete method for exerting the following loading, which equivalents to a torque, in the dynamic model were introduced, and the effect and influence of rigid body in the static and dynamic models were discussed. The comparison on the calculated results from using the static and the dynamic models explained that the method of dynamic mondel is feasible.
