摘　　要：为提高核电站专用起重机的抗震安全性能,根据地震激励下起重机安全分析评估的重要性,探讨结合专用桥式起重机工况采用静态和动态相结合的抗震评估流程方法,研究最大反应谱法在桥式起重机的应用,结果表明:桥式起重机结构随着小车位置、吊钩位置、吊载状态改变具有不同的模态特性,地震激励下的动态特性与反应谱的固有频率和参与振型相关。In order to improve the seismic safety performance of special cranes for nuclear power plants,based on the importance of safety analysis and evaluation of cranes under earthquake excitation,in this paper,the application of maximum response spectrum method in bridge crane was studied by adopting the seismic evaluation of bridge crane under static and dynamic working conditions,Results show that with the change of trolley position,hook position and load state,the structure of bridge crane presents different modal characteristics,and the dynamic characteristics under earthquake excitation are related to the natural frequency of response spectrum and vibration modes.
