大型核电汽轮机主机设备的抗震性分析

Seismic Resistance Analysis of Host Equipment of Large Nuclear Power Steam Turbine

文章分析了某大型自主设计半转速核电汽轮机主机设备的抗震性,参照等效静力计算法,加载地震载荷,进行主机设备滑销系统的破坏性强度校核;并以低压内缸为例着重进行了地震反应谱分析。

This paper analyses the seismic resistance characteristics of host equipment of a large self-designed half-speed nuclear power steam turbine. According to the equivalent static calculation method, the paper carries out the destructive strength check of the host components sliding key in the seismic load and the seismic response spectrum analysis with the example of low pressure inner cylinder.
