Design and Dynamical Analysis of New Light Deployable Bridge

摘要

摘要: 为保障人员迅速跨越沟渠、谷地等人工或天然障碍,研制了一种新型的轻型可展军用桥梁.该桥采用剪式铰和套筒可展机构实现轴向展开,用电机牵引主动索,展开至设计位置后锁定成工作状态.分析了预应力索和加劲桁架机构在减小桥梁变形、提高承载力方面的作用;制作缩比模型并进行了展开试验验证.研究结果表明:预应力索的设置使桥梁挠度从1/114减小到1/386,加劲桁架使桥梁承载力提高35.1%;该结构形式能稳定展开并投入使用,模型试验结果与展开的仿真结果吻合.

Abstract: To rapidly across ditches, valleys and other artificial or natural barriers for personnel, a new light deployable military bridge was developed. Scissors and sleeves are adopted to realize the axial deployment. A motor is used to drove a main cable to expand the bridge until it reaches a designed location, and then the bridge is locked. The functions in reducing deformation and enhancing bearing capacity were analyzed for the prestressed cable and brackets. A reduced-scale model for this bridge was made, and the test validation was carried out. The research results show that bridge deflection decreases from 1/114 to 1/386 because of setting the prestressed cable, and the bearing capacity increases by 35.1% due to the brackets. The structure can be successfully deployed and put into use, and the test result is in good agreement with the simulation one.
