热电机组基础结构动力特性实测与数值分析

DYNAMIC TEST AND NUMERICAL ANALYSIS OF DYNAMIC CHARACTERS OF A TURBO-DYNAMO FOUNDATION

针对一个振动超标的大型热电机组基础的工程实例，采用动态实测与有限元数值分析相结合的方法，得到了结构振动模态参数．这两种方法的综合使用，可以保证所得结果正确、可靠，并为结构减振设计提供依据．

This paper presentS a structural vibration teet and a numerical analysis ofan aCtUal large size turbo-dynamo foundation. Based on both of field test andFEM together the reliable results can be obtained and the vibration control designcan be carried out.
