基于不同标准半速汽机刚性基础动力特性分析

摘要

Taking the rigid foundation of half speed turbine generator of a domestic AP1000 nuclear power plant as an example,respectively accord-ing to the manufacturer’s standard and our GB 50040—96 Power Machine Foundation Design Specification,this paper made finite element modeling and dynamic characteristics analysis using SAP2000 software,and compared the results of different standards,the results showed,although the rigid foundation amplitude frequency curves had some difference in different standards,but could meet various specification limit value requirement.%以国内某AP1000核电站半速汽轮发电机刚性基础为例，分别根据厂家标准及我国GB 50040—96动力机器基础设计规范，采用SAP2000软件进行有限元建模及动力特性分析，并对采用不同标准的结果进行对比，结果显示，不同标准下刚性基础幅频曲线虽有差异，但均能满足各个规范限值要求。
