摘　　要：介绍了利用ANSYS对弧齿锥齿轮进行瞬态啮合的前置处理、划分网格、使加约束的方法。基于目前弧齿锥齿轮的应力分析研究现状。对齿面啮合质量进行了齿面接触分析(TCA),并且利用在CAE方面有很强能的ANSYS软件对弧齿锥齿轮进行啮合状态下的动态仿真[5-7],得到较为准确的齿面接触应力和齿根弯曲应力。建立了弧齿锥齿轮三维有限元非线性接触模型,对弧齿锥齿轮在一定的转速和负载转矩下进行了动态啮合仿真,得到了一个啮合周期下的齿轮齿面接触应力和齿根弯曲应力的变化规律。进行了轮齿加载接触分析(LTCA),得到了轮齿啮合传动中的齿面接触应力、弯曲应力变化过程。该方法可以进一步为弧齿锥齿轮强度分析和疲劳寿命计算提供理论依据。It introduced the method of preprocessing of instantaneous generating,meshing and imposed restriction to the spiral gears by ANSYS.Based on the research status of the recent stress analysis of spiral bevel gear,quality of tooth surface meshing was done with tooth contact analysis（TCA）,and by using ANSYS software that had very strong ability in CAE,it carried out dynamic simulation to spiral bevel gears under meshing condition,getting a more accurate tooth surface contact stress and tooth root bending stress.The three-dimensional nonlinear finite element contact model of spiral bevel gear was established,and dynamic meshing simulation was carried out on spiral bevel gear under the certain rotational speed and load torque,getting gear tooth surface contact stress and tooth root bending stress change rule under a mesh period.The loaded tooth contact analysis（LTCA） had been presented,getting the gear tooth meshing tooth surface contact stress,and the bending stress changing process.This method can further provide theoretical basis for the spiral bevel gear strength analysis and fatigue life calculation.
