摘　　要：采用固定界面模态综合法对多平行轴齿轮传动转子系统临界转速的计算进行了分析,并应用MATLAB对分析过程进行了编程,结果表明使用MATLAB程序提高了计算效率。最后以某具体多平行轴齿轮传动转子系统—发电机设备为例,求出了系统前四阶临界转速,讨论了系统主要结构参数对临界转速的影响。The fixed boundary modal synthesis method is applied to analyze the critical speed of multistage geared rotor system. And the analytical process of the system has been programmed and calculated by MATLAB. The results of the study indicate that using MATLAB program can improve the efficiency of the calculation. Finally, the prior four order critical speeds of thesystem are figured out through the example of practical multi-stage geared rotor system-generator set, The influence of the main construction parameters of the system on critical speeds is discussed.
