| 摘 要： | 在采用有限元法计算转子系统的固有频率时,通常把转子系统化为刚性圆盘、轴段、和轴承座等单元,先计算出各单元的运动方程,然后把各单元组合起来形成系统的运动方程。文章把刚性圆盘和弹性轴段视为同一单元处理,其结果计算更为准确、编程更为简单。同时文章也给出了计算转子系统临界频率的一种较好方法。

| Abstract: | In computing the critical speed with the finite element method, the rotor system is usually changed into rigid discs, elastics axis抯 and bearings, then writing out their movement equations and making them up into a rotor system equation. This paper looks the rigid disc and elastic axis as a unit,it would became more reasonable theoretically and easier to program. A good method of computing critical speed of rotor system is also given. |
