用有限元法求解减速机齿轮轴临界转速

Finite Element Analysis to Determine Critical Revolution of Reducer Gear shafts

通过有限元建模方法,运用ansys中lanzcos方法对齿轮轴进行模态分析,得到减速机齿轮轴横向振动的固有频率特征,并根据频率结果确定齿轮轴的临界转速。

A model that is established by the means of finite elements performs modal analysis on the gear shaft by using Lanzcos approach in ansys and obtain the natural frequency characteristics of the gear shaft in lateral vibration. With this result, the critical revolution can be determined.
