Abstract: 将板梁桥等效为正交异性板,车辆等效为等间距常速度在正交异性板上移动的一组荷载。根据弹性板理论、HALMITON’S原理和模态叠加原理,得到了系统状态方程,并基于规则化技巧推导了状态空间移动荷载识别方法。数值模拟和试验结果表明,该方法用挠度或应变识别车辆的轴重和轮载都是有效、可行的。
The slab-on-girder bridge is modeled as orthotropic plate,and the vehicles are modeled as a group of loads moving on top of the bridge deck at fixed distance and constant speed.The state equation of the system is obtained on the basis of theory of elastic plate,Halmiton’s principle and the superposition principle. Based on the regularization technique a load identification method is developed in state apace. Both the numerical simulation and laboratory tests show that the method is effective to identify the axle loads and the individual wheel loads by strains or displacements. 还原
