The global and local vibration of gantry crane will occur when it is working. To assure the driver’s comfort and security as well as the duration of the crane, analysis of the dynamic rigidity of the crane is necessary. In this paper, the ANSYS software was utilized for modal analysis of the crane under practical restriction, and its inherent frequencies under fully loaded condition were obtained. Finally, the weakness of the crane structure was found by the sensitivity analysis of dynamic characteristics, and the improvement measures were put forward. This work provides a reference for dynamic analysis and optimization design for crane structures.
