基于APDL语言的螺旋齿轮参数化精确建模

本文研究了渐开线圆柱螺旋齿轮的参数化有限模型的建立方法。通过采用对话框实现外部参数控制,记录点线面等参数实现内部参数控制及自下而上、等分齿体、旋转复制的建模方法,实现了基于APDL语言的参数化建模,并进行了有限分析。结果表明:该方法建立的有限元模型具有几何形状精确,单元形状规则,计算准确的特点,具有独立图元的性质,可以实现任意螺旋齿轮建模。

Parameterization Exact Modeling of Helix Gears Based on APDL

Establishing method of FE model of involute cylindrical helix gears is studied in the paper.By defining the dialogue to control external parameter,recording the parameters generated in the process of establishing model(such point,line and area etc.) to control internal paratmeters,and adopting the methods of from down to up,division helix gears,revolution copy to establish model,its the parameterization model is realized by APDL,based on that,do FE analysis.The results show that the FE model established by ...
