摘　　要：依据通用门式起重机金属结构的受力特点,针对主梁与支腿传统连接形式的不足,提出2种改进方案,并从制造难度、结构受力等方面对这2种结构形式进行对比,利用Pro/E进行三维建模,运用Ansys软件进行有限元计算。通过对比分析,找出一种较优的结构形式并加以应用。Based on the force characteristics of metal structures of universal gantry cranes,two improved schemes are put forward aiming at the defect of traditional connection types between the girder and crane outriggers,and both schemes are compared in aspects of manufacture difficulty,structural force,etc.3-D model is built by Pro/E,with the finite element analysis by Ansys software.Through comparison analysis,a better structural type is found out for application.
