【摘要】 AP1000是西屋公司开发的先进非能动压水堆。本文描述了AP1000主控室设备(PDSP和SDSP机柜)抗震鉴定试验的试验目的、试验装置、试验方法、试验内容和试验结果。试验目的在于考核设备的刚度、强度以及其在地震载荷作用时和作用后的性能指标。试验在中国核动力研究设计院核级设备鉴定中心进行。试验中通过正弦扫描和白噪声探查了样机三个轴向的固有频率及阻尼比,并采用多频波法在样机的三个轴向同时输入模拟加速度时程激振,利用地震台台面加速度作为控制信号完成抗震鉴定试验。试验结果表明,样机在试验中及试验后结构完整,功能完好,满足规范要求。更多还原

【Abstract】 Background: AP1000 is a advanced passive PWR which designed by the Westinghouse.Purpose: The purpose of the seismic qualification test is to obtain test data that will demonstrate structural integrity and functionality of AP1000 MCR equipment during and after exposure to the dynamic effect of seismic load.Methods: The test was performed at the Nuclear Equipment Qualification Center(NEQ) of Nuclear Power Institute of China(NPIC).The dynamic characteristics of specimens are detected by sine sweep and random input respectively.Multi-frequency method is applied along three orthogonal axis of the specimen in seismic qualification tests.And the seismic qualification tests are taken by using the acceleration on surface of the shake table as the control signal.Results: The structural integrity and the operability of the specimen are perfect during and after the seismic qualification test.Conclusions: Therefore,the AP1000 MCR equipments(PDSP and SDSP) pass the seismic qualification test.更多还原
