| 摘 要： | 整体传递系数法是在传递系数法的基础上,引入整体矩阵实现多子结构整体传递的一种用于转子系统动力特性分析的新型方法.整体传递系数法对于解决多转子(或机匣)相互耦合系统的问题有其独特的优点:节省计算时间,节省内存,采取状态参量中的位移项代替力项,可以消除传统的传递矩阵中的数值不稳定现象.利用此方法进行了多转子耦合系统的临界转速和振型的计算,结果表明,计算速度和数值的稳定性与其它传递矩阵法相比具有明显的提高.

| Abstract: | Whole Transfer Coefficient Method (WTCM), which was investigated and presented on the basis of Transfer Coefficient Method (TCM), is a new method of dynamic characteristics analysis of rotor system. In dynamic characteristics analysis of coupled multi rotor system, it has many advantages, good enough calculation accuracy for practical use, fewer memories and less computation time. The critical speeds and modes of coupled dual rotor system are calculated by WTCM. The results show that the computing speed and stability of numerical value are greatly improved compared with other Transfer Matrix Methods (TMM). |
