摘要
以美国第三代压水推核电站AP1000为研究对象,对典型的结构-设备耦合计算模型与结构模型进行抗震分析对比计算,并研究了不同频率比下的结构设备耦合抗震效应,分析结果表明:大质量比设备对耦合体系的影响总是不利的,且与设备、结构的固有频率差值呈正相关;设备使结构自振频率降低的现象在越低阶次的模态表现越剧烈;该工程,频率比为0.5左右的能够兼顾良好的抗震性能和经济效益。
Based on AP1000,the third generation PWR nuclear power station of the United States,the seismic analysis of structure-equipment system and structure model is carried out by using finite element software ANSYS.The composite system including large-mass equipment and spatial connection is summarized by dynamic interaction rules and characteristics of structural system.Through the analysis of the anti-seismic effect of structural equipment under different frequency ratios,the analysis results show that for AP1000,the frequency ratio of about 0.5 has good anti-seismic performance and economic benefits.
