摘　　要：针对军用桥梁装备通载状态下易发事故的问题,以某型轮式冲击桥为研究对象,分析桥跨结构与规定荷载。利用有限元分析方法,计算通载状态下桥跨的位移、应力及变形。根据计算结果,确定以挠度、位移和应力作为监测参数选择传感器,采用基于模态保证准则(modal assurance criteria, MAC)的有效独立法(effective independence,EI)优化传感器布设方案,采用无线数据传输构建监测硬件系统,设计硬件模组箱。基于LabVIEW平台开发上位机软件,实现数据采集、数据解析、状态显示与安全预警功能。试验结果表明:该监测系统能够有效反映通载状态下桥跨的姿态信息,实现事故提前预警。Aiming at the problem that military bridge equipment is prone to accidents under the state of on-load, a certain type of wheeled impact bridge is taken as the research object to analyze the bridge span structure and the specified load. The finite element method is used to calculate the displacement, stress and deformation of the bridge span under f on-load. According to the calculation results, the deflection, displacement and stress are selected as the monitoring parameters, and the effective independence(EI) method based on modal assurance criteria(MAC) is used to optimize the sensor layout. The monitoring hardware system is constructed by wireless data transmission, and the hardware module box is designed. The host computer software is developed based on LabVIEW. The functions of data acquisition, data analysis,status display and safety warning are realized. The test results show that the monitoring system can effectively reflect the attitude information of the bridge span under on-load, and realize the early warning of accidents.
