摘　　要：为计算分析核电专用桥式起重机在承受地震载荷时结构的应力响应情况,文中参考《核电厂专用起重机设计准则》和ASME NOG-1等相关标准建立了起重机物理模型,并设定其边界条件与自由度,使用Ansys Workbench反应谱分析模块加载该起重机相应地区的地震楼层谱,完成不同工况下的静力、响应力计算。结果表明,该起重机在运行安全地震震动(SL-1)和极限安全地震震动(SL-2)下符合相关规范应力标准,对同类设备抗震分析具有一定的借鉴意义。In order to calculate and analyze the stress response of the bridge crane structure for nuclear power plants under earthquake loads,a physical model of the crane was established with reference to the Design Criteria for Special Cranes for Nuclear Power Plants,ASME NOG-1 and other relevant standards,and boundary conditions and degrees of freedom were set.The seismic floor spectrum of the corresponding area of the crane was loaded by Ansys Workbench response spectrum analysis module,and the static force and response force under different working conditions were calculated.Results show that the crane meet stress standards of relevant codes under safe earthquake(SL-1)and extreme safe earthquake(SL-2),which has certain reference significance for the seismic analysis of similar equipment.
