摘　　要：利用大型有限元分析软件Msc.Marc的直接约束法,建立了某航空减速器弧齿锥齿轮副多齿啮合的三维有限元非线性接触分析模型,该模型可同时实现转矩和运动的传递。基于该模型,对齿轮副进行了一个啮合周期的准静态啮合仿真分析,给出了准静态啮合时轮齿的接触状态、接触应力、齿根弯曲应力及主从动齿轮的转矩和转速随啮合位置变化的规律。分析表明,本文得到的结果非常符合实际啮合规律,也验证了模型的正确性。By using the large finite element method software MSC.Marc,A 3-D nonlinear contact analysis model for a pair of spiral bevel gear with several meshing teeth pairs is established.Based on the model,A quasi-static meshing simulation in the case of definite torque and rotary speed are carried out in a meshing period.The numerical results which indicating the variety of the contact status,the contact stress,the bending stress in the location of teeth root and the torque and rotary speed of gear pair vs.the different meshing position are presented,and show a very good agreement with the meshing rules in reality,and simultaneously,the rationality of the model is be verified.
