基于ANSYS的双圆弧齿轮接触应力有限元分析

Finite Element Analysis of Contact Stress for Double-arc Gear Based on ANSYS

利用ANSYS软件的参数化设计语言APDL建立双圆弧齿轮的三维有限元单齿对接触静态模型,并对模型划分网格,施加载荷,获得了双圆弧齿轮的静态接触应力云图;基于ANSYS/LSDYNA建立了柔性体多齿动态接触模型,并对齿轮进行了动态接触分析。计算分析结果为双圆弧齿轮的设计和使用提供了理论依据。

Three dimensional finite element model of static contact for single tooth-pair of double-arc gear was established according to APDL language embedded in ANSYS, and the distributing graph of static contact stress was obtained after separating reseau and loading. Meanwhile, the dynamic contact model of many teeth based on ANSYS/LS-DYNA was built up and the dynamic contact was analyzed. The results provided theoretical basis for the design and application of double-arc gear.
