摘要
介绍了汽轮发电机横向振动频率（临界转速）的有限元方法，它与Prohl法比较在编程时逻辑关系简单，省掉大量叠代过程。
This article gives Finite Element Method of lateral critical frequency(critical speed) of turbogenerator. FEM spends computer time shorter than Prohl method and program of logic of FEM is simply, but program of logic of Prohl method is very difficult.
