摘　　要：以某三代核电设备安全壳喷淋泵为对象,利用有限元对整个系统进行建模,完成了该系统抗震性能、各部件模态和应力、结构屈曲以及连接螺栓应力的分析和评定,并进行了现场振动频率测试。结果表明,此安全壳淋喷泵满足规范要求,与设备模态试验情况符合较好。本研究可为后续安全评审和设备鉴定提供研究支持。In this paper, taking a containment spray pump in a third generation nuclear power plant as an example, the whole system is modeled and analyzed. The aseismic performance, modal and stress of each component, structural buckling and connection bolt stress of the system are analyzed and evaluated , and on-site vibration frequency is tested. The results show that the containment spray pump meets the requirements of the code, and the results are in good agreement with that from the equipment modal test, which provides research support for the follow-up safety assessment and equipment appraisal.
