考虑粗糙度影响间接测量梁刚度的损伤识别方法参数研究
|
摘要
利用检测车在桥梁上运行可进行桥梁结构损伤识别,针对该间接测量技术的诸多局限性问题,基于车桥耦合模型,提出了通过检测车在桥梁上运行,利用安装在检测车辆上的传感器所得的动力响应信号来识别梁单元弯曲刚度,进而进行结构损伤识别的间接测量方法。在此基础上,考虑了路面粗糙度等因素对间接量测方法的影响,以均匀设计法和控制变量法为研究工具,通过数值模拟对检测车速度、检测车质量、检测车阻尼、桥梁模态阻尼比等4个参数进行研究分析。研究结果表明,检测车质量、检测车阻尼,以及桥梁阻尼比等相关参数在适当的范围,可以大幅度提高该方法的使用效果,进而有助于推动间接量测技术在桥梁结构损伤识别中的实际应用。
Damage identification in bridge structures using the moving vehicle can be carried out. In view of many limitations of indirect measurement technique for structural damage identification of bridges,based on a vehicle-bridge coupled model with consideration of the road surface roughness,this paper presents a new indirect approach by using the identified bending stiffness for structural damage identification of a bridge from the dynamic response records of a test vehicle passing over the bridge. Four parameters of this new indirect approach,namely,the mass,the speed of the vehicle,the damping of the vehicle,and the modal damping ratio of bridge,were analyzed by using the uniform design method and variable control method in numerical simulation. It shows that the new indirect approach for damage detection of bridge is feasible and effective in the range of appropriate parameters. It is significant for the application of indirect measurement technique in practical projects.
