中文摘要：

在实际转子中“陀螺效应”在一定程度上会影响临界转速．本文采用ANSYS模拟的方法计算转子的临界转速并研究其“陀螺效应”．通过计算几个长度相同半径不同的简单梁的临界转速，确定梁跨比不同时“陀螺效应”对临界转速影响．

英文摘要：

In practice ＂gyroscopic effect＂ will affect the critical speed to some extent. This paper uses ANSYS simulation method to calculate the critical speed, and the impact of ＂gyroscopic effect＂ on the critical speed. Comparison of the critical speed of the same length and gyroscopic effect of its critical speed, in order to determine on the critical speed. different radius of a simple beam, and compare the the beam ratio, the extent of the ＂gyroscopic effect＂
