摘要
提出了大型非经典阻尼系统动力分析的动态解耦方法，同时在特征值问题的求解和动力响应的计算中完全避免复数运算．方法适用于无阻尼陀螺系统、非经典阻尼系统（包括阻尼陀螺系统），且不论系统亏损与否．
This paper gives a dynamic decoupling approach for the analysis of large scale non classically damped system, in which the complex number computations were completely avoided not only in solving for the eigenvalue problem but also in the calculation of the dynamic response.The analytical approach for undamped gyroscopic system, non classicaly damped system, including the damped gyroscopic system were unified. Very interesting and useful theoretical results, practical algorithms were obtained which is applicable to both non defective and defective systems.
