结构健康监测中传感器布点优化的研究进展

Advances in Optimal Sensor Placement for Structural Health Monitor

传感器布点优化(OSP)关系到结构监测系统(SHM)所采集信息的准确性及可靠性,是结构模型修改、损伤识别、状态评估的基础,是SHM中一个至关重要及热点研究问题。从优化目标(即传感器布点准则)及优化算法的角度对目前SHM中OSP方法进行综述,最后提出了对此领域中需要进一步研究的几个问题。

Optimal sensor placement(OSP) in structural health monitor system(SHM) is relative to the accuracy and credibility of the collected information by sensors.It is the foundation of modal updating,damage detection and structural evaluation.Optimal sensor placement(OSP) is a very important and hot researched problem in SHM.In the view of the objective(criteria of sensor placement) and algorithm of optimization model,an overview of OSP in SHM is presented.Some problems are proposed for further research.
