摘　　要：以某单机容量1200MW、工作频率为25Hz的半速汽轮发电机基础为背景,设计制作了1:10的缩尺模型。针对汽机基础的各项设计要求,采取一种正弦激振的方法进行基础模型传递率测试,以此检验柱顶隔振的汽轮发电机基础设计是否达到所要求的隔振效率。Taking the basis of a half-speed turbo-generator with a single unit capacity of 1200MW and an operating frequency of 25Hz as the background,which designed and produced 1:10 scale model.According to the design requirements of the turbine foundation,a sinusoidal excitation method is adopted to test the transfer rate of the basic model,in order to test whether the foundation design of the column top vibration isolation turbine generator achieves the required vibration isolation efficiency.

关 键 词：汽轮发电机基础 柱顶隔振 传递率
