摘要

利用有限元软件对某公司设计的83 m跨度A5型门式起重机的刚度进行分析，求得的主梁挠度超出《通用门式起重机》(GB/T14406-93)的规定，且结构产生较大的侧向位移.通过对刚性支腿结构设计进行修改，使得主梁最大挠度下降69.2%，侧向位移下降62.6%.

Abstract

Finite software was used to research the A5 Gantry Cranes designed by a company

whose span was 83 m. The research results indicate that the deflection of girder oversteps the formulations of General purpose gantry cranes (GB/T14406-93)

coupled with a big lateral displacement. After a simple modification of the structure design for the rigid legs

the deflection of girder and the lateral displacement have reduced by 69.2% and 62.6%

respectively.
