Finite element analysis of involute spur gear based on ANSYS and method of improving

通过三维机械设计软件SolidWorks构建直齿圆柱齿轮实体模型,运用有限元分析软件ANSYS对齿根进行应力分析计算,得出齿根弯曲应力分布云图,通过与理论分析结果的比较,说明ANSYS在齿轮计算中的有效性。最后针对应力分布云图,对齿轮结构提出了改进方案,为齿轮的优化设计提供了可靠的理论依据。

The involute spur gear model is built in SolidWorks——3D mechanic design software, then analyzes stress of gear tooth by the finite element software ANSYS, so obtain the contour of bending stress distribution of tooth root. By contrast with theoretical analysis, it illustrates the effectiveness of the application of ANSYS in gear calculation. According to the contour of stress distribution, improve the structure of gear tooth, so it can provide the dependable basis for optimization design of gears.
