核级UPS是核电站的重要设备之一,对核电厂的安全稳定运行起重要作用。为保证设备质量和可靠性,核级UPS需要进行抗震强度分析确保其通过抗震试验鉴定,使其满足当电厂实际发生地震的烈度在鉴定试验抗震响应谱的包络范围内设备能够安全运行。使用HyperWorks软件对核级UPS进行结构抗震强度分析,以确保其结构设计满足核级设备的抗震要求。The nuclear-class( 1E class) UPS,as the significant power supply in nuclear power plant,plays a dual role in protecting and controlling the power supply,which is vital to the safe and stable operation of nuclear power plants. In order to improve reliability of power supply,UPS of nuclear power plant requires enough anti-earthquake ability,which means that the mechanical properties of the UPS during the process of designing and producing should be fully considered. What 's more,for ensuring the safe operation of equipment,it is indispensable for effective structural strength analysis and anti-earthquake analysis to make UPS cover earthquake response spectrum of given. In this paper,we innovatively use Hyper Works software into structural anti-earthquake intensity analysis of nuclear-grade UPS,to ensure the structure design satisfies the demands of nuclear-class devices
