| 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. |
