摘　　要：针对动态车辆超重检测,建立了一种新型的高速动态车辆称重方法。桥梁采用简支梁模型,车/桥相互作用模型化为两个具有固定间距点力匀速通过桥面。利用安装在桥梁下面的应变传感器测量车辆经过桥面引起的桥梁应变,通过积分运算消除车辆振动对计算结果的影响,进而获得动态车辆的载重值。试验结果表明该方法可以较准确地进行高速动态车辆载重的测量。This paper provides a new high-speed weigh-in-motion method. The deck was modeled as a simply supported beam and the vehicle/bridge interaction force was modeled as two-point loads with fixed axle spacing, moving at constant speed. The strain sensors under the bridge were used to measure the bridge strain when the vehicle moved across the bridge, the integral operation was used to eliminate the effect of the vehicle vibration to get the moving vehicle load. Results of experiments showed that the identification method is effective.
