针对桥梁上时变移动车载 ,提出了两种桥梁模型、四种移动车载间接识别方法和两种不同解决方案 ,并通过模型实验对上述不同桥梁移动车载解决方案进行验证。仿真和试验结果表明 :虽然各种车桥参数对识别结果都有不同程度的影响 ,但每种解决方案都能有效识别桥梁移动车载且以“时域法”和“频时域法”识别精度较高、实用性较强 ,可推荐用于现场桥梁移动车载识别。 Two kinds of bridge models, four kinds of indirect recognition methods for mobile vehicles and two different solutions are proposed for time-varying mobile vehicles on bridges, and the model solutions are verified by the model experiments. The simulation and experimental results show that although all kinds of axle parameters have different degrees of recognition results, each solution can effectively identify the bridge mobile vehicle and the identification accuracy by “time domain method” and “frequency-time domain method” Higher, practicality, can be recommended for on-site bridge mobile vehicle identification.
