挠性转子横向振动分析的传递矩阵法

介绍了一种分析挠性转子横向振动特性的传递矩阵法。它由系统的整体传递矩阵及边界条件得到频率方程，由此来计算转子的各阶固有频率；然后利用传输特性方程，求得转子任意截面上的状态向量，从而得到相应的振型函数。研制了一套用于分析挠性转子横向振动特性的专用软件包，可给出转子的各阶固有频率和相应的振型函数。最后，给出了一典型算例。

Transfer Matrix Method for Analyzing the Transverse Vibration of Flexible Rotors

A kind of transfer matrix method for analyzing the transverse vibration characteristics of flexible rotors is introduced. The frequency equation canbe obtained from the whole transfer matrix and boundary conditions of the system, therefore the intrinsic frequencies of the rotor can be calculated. Then byutilizing the transfer equation of the transverse vibration, the state vector ofany section can be acquired, and consequently the vibration modes are got. Aspecial software package for analyzing the transverse vibration characteristicsof flexible rotors is developed, which can give out the intrinsic frequencies andvibration modes. Finally, a typical example is set forth.
