【摘要】 阀体是换流站阀厅内的主要悬吊荷载,利用staadpro有限元软件,用反应谱法分析悬吊阀体在地震作用下的结构反应特点,并与简化设计模型对比。分析表明,悬吊阀体对阀厅整体结构的抗震影响有利,但程度较小。由于悬吊阀体有6组,每组阀体又有多个单元模块,在地震作用时阀体的振动形式很多,悬吊阀与整体结构在地震作用时的相互影响很复杂,有待进一步研究。更多还原

【Abstract】 Valve body is the main suspended load in valve hall of converter stations.The characteristics of suspended valve body responses under earthquake are analyzed using response spectrum method by finite element software,Staadpro.Results are compared with simplified design model.Analysis shows that suspended valve body has beneficial effect on quake resistance of entire hall structure,although the extent is quite small.Because there are 6 banks of valve bodies,and each bank has several modules,there are numerous body vibration forms under earthquakes.The interactions between suspended valves and entire structure under earthquakes are very complicated,requiring further studies.更多还原
