基于ANSYS的渐开线齿轮建模和有限元分析

Modeling and Finite Element Analysis of Involute Spur Gear Based on ANSYS

利用直角坐标系下的渐开线方程,通过坐标转换原理得到在ANSYS环境里适用的方程组,从而达到比较精确建立轮齿模型的目的.并对建立的模型进行初步有限元分析.经过应力分析后,可以证实该种方法建立的模型是比较精确的.建立比较精确的分析模型,对准确地掌握轮齿应力的分布特点和变化规律具有重要的意义.

The appropriate equations on ANSYS is created with the Cartesian coordinate system involute equation so as to establish an involute gear model which is more precise. The model is analyzed with finite element, which can confirm model establishment and make this kind of method accurate. Establishing an accurate model has important significance for accurately mastering the distribution characteristics and change laws of the dint of gear.
