摘　　要：对岸桥起重机的有限元建模、约束处理作分析与探讨,在此基础上就岸桥起重机系统进行模态和动态响应分析,得到起重机系统前十阶振动频率、振型和位移响应时间历程。该结果对岸桥起重机设计中如何避免在工作频率范围上共振现象的产生及限制在动载时过大动变形的产生有实际意义。A finite element model and its boundary conditions of the gantry crane are established in this paper. The first ten natural frequencies, the corresponding mode shapes and time-history of displacement response are given out based on the analysis of the modes and dynamic response of this gantry crane system. The calculation and analysis may be helpful for preventing the gantry crane from working on resonant region and for keeping the oversize dynamic deformation under restraint, which can be applied to design gantry crane systems.
