结构健康监测中基于多重优化策略的传感器布置方法
Multiple optimization strategies based sensor placement method for structural health monitoring
摘要
Abstract
How to determine the quantity of the sensors and the optimal sensor placement to satisfy the testing requirements is a primary problem to be solved in the structural health monitoring.A new step-by-step sensor placement method based on the multiple optimization strategies was proposed.The initial sensor placement was firstly obtained by the QR-factorization.Then the maximum off-diagonal element of the modal assurance criterion（MAC） matrix was taken as the target function.The freedoms of the structure by the forward sequential sensor placement algorithm were gradually added to reduce the off-diagonal element of the MAC.Considering the change extent of the off-diagonal element＇s mean value,the quantity of the sensors could be determined.Finally,the plan of optimal sensor placement could be obtained by the dual-structure codes-based generalized genetic algorithm.In the end,the analysis of the optimal sensor placement for the 600 m Guangzhou New TV Tower（GNTVT） was performed.The results show that,for the structures with stiffness mutation（like the main tower and antennary mast of GNTVT）,the sensor placement had better to be considered for each part separately.关键词
