摘　　要：论述了六弹簧支承的转子系统在刚度Ｋ＝ ３ｋ 时，在临界转速计算中的误差及原因，得出了按实测Ｋ 计算临界转速与实测临界转速较为一致的结果。此外，认为弹性系数计算时还应考虑侧向刚度的影响以及临界转速计算时还应考虑阻尼对其的修正。The error and master sheet of calculating critical speed is presented for rotor system with six spring elastic support,if rigidity is K=3k.Then concept of real measuring K is presented,calculating critical speed using real measuring K and real measuring critical speed have same result.In addition,cross rigidity and damp must be considered for calculating critical speed.The correction formula is presented and have been tested,it has satisfactory result.$$$$
