摘　　要：结合某40.5 t门式起重机,利用有限元计算工具,对整机进行模态分析,得出该起重机的固有频率,并进行刚性分析,从而选择一种较为合理的结构形式。该方法可为大型港口设备的刚度设计、计算和分析提供参考。Combined with a 40.5 t gantry crane,to derive the natural frequency of the crane,a modal analysis and a stiffness analysis of the whole machine are carried out by using finite element calculation tools,so as to select a more reasonable structural form.This method can provide reference for the stiffness design,calculation and analysis of large port equipment.

关 键 词：固有频率 刚度 模态分析
