摘　　要：通过理论计算能够得到齿轮齿根弯曲疲劳强度,但理论计算方法未考虑径向压应力对齿根弯曲强度的影响。在UG NX 2环境中建立标准渐开线圆柱直齿轮,在UG结构分析模块中对轮齿进行静态结构分析并得到应力分布图,仿真精度与解算器和网格划分关系密切。理论计算与虚拟仿真结果均满足许用应力要求。该方法在同一软件环境中实现了对象CAD与CAE的结合,能够辅助模型结构的优化设计,有助于提高设计效率和产品质量。The gear tooth endurance bending strength was obtained through theoretical calculation but the radial compressive stress influence to the bending strength was not considered.The normal involute cylinder gear model was built under UG Background. Tooth structural analysis and stress envelope was brought out. The resolver and gridding demarcation is affect the simulation precision closely. The both results of theoretical calculation and structural analysis was satisfied to the requirement of admissible stress. The combination of CAD and CAE was achieved in one software background. This method could help the mechanism optimized design rapidly and make a useful effort to increase efficiency and quality of product.
