摘　　要：轨道式集装箱门式起重机因其结构合理、安全可靠、稳定性好等优点,在很多新建集装箱码头及堆场被广泛应用。起重机门架结构主要由主梁、端梁、支腿、下横梁、马鞍及走台栏杆、梯子附件等组成,是门式起重机的重要受力构件。文中利用有限元分析软件创建门架参数模型,考虑到起重机的工作环境、工作状况及小车运行极限位置的不同,将起重机划分成不同工况并对其进行静刚度和强度分析,保证其具有足够的强度、刚度及稳定性。Rail container gantry crane is widely used in many new container terminals and yard because of its reasonable structure,safety,reliability and good stability.The gantry structure of crane is mainly composed of main beam,end beam,leg,lower beam,saddle and walking rail,ladder accessories,etc.It is an important load-bearing member of portal crane.This paper creates a parametric model of the gantry on the basis of finite element analysis software.Taking into account the different working environments,working conditions and trolley operating limit positions of the crane,the crane is divided into different working conditions and static stiffness and strength analysis is carried out to ensure that it has sufficient strength,stiffness and stability.
