同轴双转子系统临界转速的敏度分析

Sensitivity Analysis in Critical Speeds of Synaxial Dual Rotor Systems

用解析法分析同轴双转子系统临界转速的敏度．以纺杯轴承系统为例，用离散法计算同轴双转子系统临界转速对各系统参数的敏度，并与解析法计算结果进行对照．给出了转子系统动态特性敏度分析应用的例子．

The analytic and discrete methods of the sensitivity analysis in dynamics of synaxialdual rotor systems are discussed in this paper. The bearing system of the rotor of open-end spinningis taken as an example to calculate sensitivites of Critical speeds with respect to some system parameters. It is presented that the contrasts exist between the calculation results of two methods. Some examples of application of the sensitivity analysis of dynamics of rotor systems are taken in thispaper.
