核电常规岛主给水泵抗震分析

Seismic Analysis of Nuclear Conventional Island Pump

以核电常规岛主给水泵为研究对象,采用ANSYS12.0软件中的"模态分析"模块对主给水泵整机进行在SSE(安全停堆地震)、OBE(运行基准地震)两类地震工况下的抗震分析。并将静强度分析结果与抗震分析结果进行叠加,对承压部件或非承压部件等进行抗震安全评定。结果表明核电常规岛主给水泵抗震符合各个工况下安全要求。

Mode analysis module of ANSYS12.0 soft is used to analyze earthquake resistant property of nuclear conventional island pump under SSE(Safe Shutdown Earthquake) condition and OBE(Operating Basis Earthquake) condition. Seismic safety evaluation has been stacked of static strength analysis and seismic analysis for pressure parts and non-pressure parts.Results indicate that seismic analysis of nuclear conventional island pump meet the requirement under all conditions.
