摘　　要：文中针对冲击电压发生器建立有限元模型,在Taft实测地震波、El Centro实测地震波和生成的Qinghai人工波3种地震输入波作用下,对冲击电压发生器本体塔架结构进行了自振特性分析,并基于时程分析法对设备结构地震反应进行分析。基于自重和地震作用组合效应,对冲击电压发生器设备结构体系关键部位的抗震强度进行验算。计算结果发现:在抗震设防标准下,本体塔架结构主要构件和关键部位的抗震强度均满足抗震安全性要求,且有较大的安全裕度。In this paper,the finite element model of impulse voltage generator is established,under the action of three kinds of seismic input waves,i.e.Taft measured seismic wave,El Centro measured seismic wave and generat-ed Qinghai artificial wave,the self-vibration characteristics of impulse voltage generator tower structure are ana-lyzed,based on the time history analysis method,the seismic response of the equipment structure is analyzed.Based on the combined effect of self weight and earthquake action,the seismic strength of key parts of impulse voltage gen-erator equipment structure system is checked.The results show that under the seismic fortification standard,the seis-mic strength of the main components and key parts of the generator tower structure satisfies safety request and also has greater safety margin.
