摘　　要：针对复合材料智能蒙皮静载响应监测下的定位识别技术开展研究,提出并设计了一种静载识别验证系统。选用碳纤维复合材料板(CFRP)为研究对象,搭建光纤布拉格光栅正交对称式传感网络对复合材料板进行静载位置识别。利用数据相关加权系数理论和算法,对加载位置进行识别,实验表明定位精度低于2 cm。设计的静载识别验证系统为CFRP蒙皮结构健康监测提供了新思路和新方法。In order to research the location identification technology of smart skin under static load response,a static load identification verification system is presented and designed.An optical fiber Bragg grating（ FBG） orthogonal symmetrical sensing network is constructed,static load position identification of composite plate is carried out,where carbon fiber reinforced plastics（ CFRP） is as a research object.The loading position is identified by using data correlation weighting coefficient theory and algorithm,and the test shows that the positioning accuracy is less than 2 cm.The design of static load identification verification system provides new idea and method for CFRP skin structure health monitoring.
