Abstract
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.
