摘　　要：应用有限元法及ANSYS软件,对小车满载和小车空载条件下的多种工况分析了QD250/50/10t-25.5型桥式起重机主梁变形及应力分布状态,通过对仿真结果和实测结果进行比较,校核了该型号主梁的强度、刚度情况,得出箱型主梁结构强度的影响因素,进而改进了主梁焊接的工艺方法,提高了产品质量,对今后桥式起重机主梁结构设计与制造提供了有益参考。The author analyzed the QD250/50/10t - 25. 5 crane girder＇s stress distribution and distortion, with the finite element software ANSYS, based on the full-load and no-load condition. The computation analysis result had indicated that the intensity and rigidity of the main girder are in conformity to the design standard. The main factors that influence the structure were also obtained from the simulation and actual measurement result, which improve the welding technology and quality, also provide reference for similar design.
