汽轮机转子临界转速及不平衡响应计算

Calculation of the critical rotating speed and unbalance response of steam turbine rotor

通过数值模拟,计算了汽轮机转子的临界转速,分析了不平衡质量存在位置对工作转速下振动幅值的影响,得出了幅值与不平衡质量所在位置的关系。

Based on numeric simulation,the critical rotating speed of the steam turbine rotor was calculated.The influence of the position,in which the unbalanced mass exists,on the vibration amplitude under working rotating speed was analyzed;and the relation between the vibration amplitude and the position of unbalanced mass was obtained.
