摘要
利用ANSYS Workbench有限元分析软件对孔穴齿轮三齿模型进行六面体网格划分,以孔穴的设计参数和齿轮的最大等效应力作为变量,采用多目标遗传算法进行优化设计。对孔穴齿轮和普通直齿轮进行静力有限元分析,计算出齿轮在工作过程中的应力,并进行了对比,发现孔穴齿轮的齿根弯曲应力相比普通齿轮下降明显,为孔穴齿轮进一步的理论研究提供必要的依据。
This paper uses ANSYS workbench to divide the cavity gear tridentate model into the hexahedral mesh,takes the gear design parameters and gear maximum equivalent stress as variable,applies the multi-objective genetic algorithm to its optimal design,makes the static finite element analysis of the cavity gears and ordinary gears and calculates the stress during operation of gears.Compared with both results,It shows that the gear root bending stress of the cavity gear decreases significanfly.The necessary basis is provided for researching on the cavity gear theory.
