摘　　要：研究转子及其支承系统振动特性优化设计方法,并以M atlab软件作为平台,开发出基于传递矩阵法的转子系统的振动特性优化设计软件,利用该软件对某一大型实验转子系统的振动特性进行优化设计,优化设计后的转子系统更具安全性,并且更加逼真地模拟实际机组的振动特性。The optimal design method of the vibration characteristic of the rotor and bearing system is researched. Taking Matlab as the software platform, the optimal design software of the vibration characteristics of the rotor system is developed based on transfer matrix method, and the software is used to optimize the vibration characteristics of a large experimental rotor system. The result show that after optimal design, the safety quality of the rotor system is better, and the simulation of vibration characteristics of real unit is more close to reality.
