摘　　要：在鱼雷转子系统中,为避免系统发生共振,常需要计算其涡动频率。鉴于商业有限元分析软件的输入参数有限,且无法满足特殊情况下的计算需求,该文根据转子系统的运动微分方程及其求解过程,运用MATLAB软件编程来计算系统的涡动频率,然后与ANSYS软件计算结果进行对比。结果表明,所编写的MATLAB程序合理,可对鱼雷推进轴系进行计算,也可进行后续开发。To avoid resonance, it is necessary to calculate whirling frequency of a rotor system. The input parameters of commercial finite element analysis（FEA） softwares are limited, and these softwares can not complete the analysis of special cases. In this paper, according to the differential equation of motion for a rotor system and its solution process, a program is coded to calculate the whirling frequency by the software MATLAB. Comparison between the results -of MATLAB and ANSYS shows that this MATLAB program is reasonable, and it can be used to calculate whirling fre- quency in flexural vibration of torpedo propulsion shafting or to perform subsequent development.
