摘　　要：DXZ32/900造桥机能自行完成过孔移位,无须地面其他辅助起重设备,机械化及自动化程度高,操作简便,安全可靠,广泛应用于高速公路、高速铁路客运专线、城市轨道交通、水利工程、国防及军事工程等领域。建立了DXZ32/900造桥机有限元计算模型,通过制梁和过孔阶段多工况的计算和分析,掌握了该机整体力学水平和应力分布,为造桥机结构的改进和进一步优化设计提供重要的基础。The DXZ32/900 bridge fabrication machine can perform bridge hole going through without other ground machines, and is designed for high mechanization and automation, easy operation, and safety. It can be widely used in highway, railway, hydraulic engineering and military engineering. The paper describes how the finite element calculation model of DXZ32/900 bridge fabrication machine is built, and how the whole machine mechanics status and stress distribution are obtained by means of the calculation and analysis. It lay a foundation for improving and optimizing the bridge fabrication machine.
