在过去的几年里，使用有限元法对转子系统进行仿真已经受到了相当大的关注。已发表的作品包括旋转惯性，陀螺力矩，轴向载荷和内部阻尼的影响的研究，但没有包括剪切变形或轴向扭矩的影响。本文推广了前人的工作，利用梁理论建立形函数和，从而包括横向剪切效应。内部阻尼不包括在内，但延长是直线前进。对非旋转轴和旋转轴的有限元分析与经典闭合梁理论分析进行了比较。
The use of finite elements for simulation of rotor systems has received considerable attention within the last few years. The published works have included the study of the effects of rotatory inertia, gyroscopic moments, axial load, and internal damping; but have not included shear deformation or axial torque effects. This paper generalizes the previous works by utilizing Timoshenko beam theory for establishing the shape functions and, thereby including transverse shear effects. Internal damping is not included but the extension is straight forward. Comparison is made of the finite element analysis with classical dosed form Timoshenko beam theory analysis for nonrotating and rotating shafts.
