Finite element modal analysis of structure of gantry crane

Dynamic performance of gantry crane directly affects the reliability and efficiency of crane.It is difficult to control the dynamic performances of gantry crane with the traditonal design method.After build-ing the physical model of gantry crane with FME,the modal analysis was carried out,and the previous natural frequencies and vibration modes of the gantry crane were obtained.Thus,the instable factors brought about structural vibration were learned,and an effective method of analyzing the structural design of gantry crane was presented.
