基于ANSYS的发动机行星齿轮组参数化建模与分析

Parametric Modeling and Analysis of Engine Planetary Gear Set Based on ANSYS

将某型号发动机行星齿轮组作为研究对象,在ANSYS软件中建立起三维模型,结合APDL语言和命令流操作对行星轮和内花键施加载荷,进行瞬态动力学分析,求解得出行星齿轮的位移和应力云图。文中网格划分相对合理,施加的约束及载荷条件接近实际工况,分析的结果对今后的设计具有一定的参考价值。

Choose one type of engine inside traction planetary gear set as the research object, then set up 3d model within ANSYS, after that put the dynamic load on planet wheel and internal spline combine with AP- DL and command flow operation , at last get the displacement and stress nephogram through transient dy- namics analysis. The grid division is reasonable and the constraints load applied is more close to the real working condition. The result of the analysis have some reference value for the design in the future.
