摘要

建立了核电站余热排出热交换器的动力模型,通过管梁单元、集中质量单元、弹簧单元及刚性梁连接单元等较准确地模拟了设备结构的动力特征,同时通过等效密度的修正考虑了液体及水动力附加质量的影响。通过反应谱动力分析和等效静力分析方法相结合,综合考虑了低阶模态的动态反应和高阶模态的静态反应,得到了安全停堆地震(SSE)工况下结构内的最大应力、支撑处的最大作用反力,以及各组件接口传递的力和力矩。结果表明,该热交换器在SSE地震事故下,仍能保证结构边界的完整性和结构强度的安全性,具有较好的安全裕度。
Dynamic model of the AP1000 passive residual heat removal heat exchanger was built,which including beam element,mass element and rigid beam connect element and considering the hydrodynamic mass effect.Response spectrum method was used in the seismic analysis which have considered the dynamic response of low frequency and static response of high frequency.The maximum response of structure was obtained under the safety shutdown earthquake condition,and the result shows that the heat exchanger can still remain the boundary completion and strength safety.
