摘要

摘要: 建立三维参数化齿轮啮合有限元模型,利用ANSYS软件对其进行仿真计算,得到齿轮啮合的接触应力变化规律.基于响应面方法综合考虑齿轮各参数的原始制造误差以及转速、载荷等不同工况对齿轮传动的影响,对齿轮啮合传动进行多次随机虚拟试验,得出其可靠度,并以定量的概率给出各参数的可靠性灵敏度.计算结果得出了各个参数原始制造误差对齿轮接触应力的影响程度.

Abstract: Rules of variation of contact stress in gear engagement were obtained by means of dynamic simulation in ANSYS after the three-dimensional parameterize finite element model was created.Based on the effects of original manufacturing errors,rotational speed and load on gear drive,expanded response surface method was adapted in multiple stochastic virtual test of the meshing gear to compute the reliability;and reliability sensitivity of each parameter was given in quantitative probability,providing a theoretical base for fatigue strength calculation and dynamic optimum design of the drive gear mechanism.The effects of different parameters’ original manufacturing error on gear contact stress were got.
