大型汽轮发电机卧式隔振结构受力分析

Stress Analysis on the Horizontal Vibration Isolation of the Large Turbine Generator

应用振动力学理论推导出二相短路工况下大型汽轮发电机定子铁心运动的动力学方程。采用Matlab软件对卧式隔振结构弹簧板所受最大切向力进行数值计算。通过对计算结果的比较分析,为卧式隔振结构的设计提供理论支撑。

Theory of vibration mechanics was applied to deduce the dynamic equation of the stator core motion of large turbine generators under the condition of two-phase short circuit.The maximum circumferential force of the horizontal vibration isolation structure of the spring plate was numerically calculated by means of Matlab software.The theoretical support for the design of the horizontal vibration isolation structure was provided by comparing the results of the analysis.
