摘　　要：本文以MZ48/1200下行式移动模架造桥机为研究对象,应用MSC.PATRAN/NASTRAN软件根据结构特点建立其整体有限元模型,选定应力较大部位以及变形较大部位为静态应力测试的布点位置,通过静应力实测结果及比较分析,同时对其静刚度和关键部位进行无损探伤,为移动模架结构安全评估提供可靠的数据。This paper taking MZ48/1200 descending bridging machine as object of study, using the software MSC.PATRAN / NASTRAN, according to its structural features setting up overall finite element model, selected parts at which the stress and deformation are higher as test point location of static stress test, and through the static stress test results and a comparative analysis and non-destructive testing of static stiffness and key parts provided reliable data for movable frame structure safety assessment.
