摘要
从理论的角度对谐波齿轮减速器的柔轮进行应力分析,依据光滑圆柱壳体模型得出沿母线方向的正应力、周向正应力、剪应力以及疲劳强度。在实验分析中,先通过ADAMS软件建立刚-柔混合模型,进行刚-柔耦合仿真验证了模型的正确性之后,通过ANSYS Workbench软件对柔轮进行动力学分析,得出了柔轮最易发生疲劳的位置及其疲劳安全系数。采用协同仿真分析法表明,计算机分析数值与理论计算数值非常接近,从而验证了理论分析的正确性。
The stress analysis of flexible gear of harmonic gear reducer was analyzed from the theoretical perspective. According to the model of smooth cylindrical shell, the normal stress along the direction of the bus, circumferential normal stress, shear stress and fatigue strength were obtained. In the analysis of the experiment,first established a rigid-flex hybrid model through ADAMS software,after rigid-flex coupling simulation validated the model,through the ANSYS Workbench software,the dynamic analysis of the flexible gear was carried out, and the fatigue safety factor and the position which was the most susceptible to fatigue of the flexible gear was obtained. The results based on collaborative simulation showed that the numerical value of computer analysis was very close to the theoretical value,which verified the correctness of theoretical analysis.
