摘　　要：核电厂燃料抓取机为抗震II类设备,需满足抗震要求。基于ANSYS和反应谱分析法对系列形式的燃料抓取机进行了详细建模和抗震分析,并对结构的应力进行了组合和评定。抗震分析时考虑了大小车地震载荷作用下马达反向驱动力或摩擦力不足导致的沿轨道滑动的效应。研究发现某在建核电站中进口门式燃料抓取机原设计抗震性能较弱,因此对自主设计的燃料抓取机提出了设计改进,并应用到CAP后续项目标准设计和CAP1400的工程设计中。分析表明,把起重机形式从改门式改为桥式,并采用悬挂式铰支人桥结构,可大幅提高燃料抓取机抗震能力。The seismic category of fuel handling machine（FHM）/s Cat. II in nuclear powerplant（NPP）. The seismic requirement is essential to meet. Base on ANSYS and response spectrum method,detail models are created and seismic analysis are pet.formed for series FHM And the stress combination and evaluation are performed. Slip effect by inadequate back-driving force or friction force during an earthquake is considered. It is indicated that the seismic capability of imported FHM in a certain abuilding NPP is weak ,which is a gantry crane. Then,the improvements and self-design are performed in the projects of CAP standardization design and CAP1400. The analysis indicates that the seismic capability of bridge crane type with suspension bridge is much better than gantry crane type for FHM.
