用奇异函数求转子系统扭振固有频率

Calculation of Torsional Vibration Natural Frequency of Rotator System by singular Function

将转子系统抽象为一等截面弹性轴扭振系统，对有任意个转子的系统，采用奇异函数及Ｌａｐｌａｃｅ变换导出了转子系统扭振时的固有频率方程。

In rolation to rotator svstem with wilful rotators,regarding the rotator systemas a torsional vibration system of plastic axle with equal section,the natural frequencyequation for the rotator system torsional vibrating is derived by using singular function andLaplace's transformation.
