| 摘 要： | 基于主动Lamb波和压电传感器网络的结构健康监测技术是一种评估航空结构健康状态的有效方法。在实际应用中,监测大型结构需要使用压电传感器网络。扫查这些压电传感器网络中的压电激励-传感通道以达到在线的结构健康监测是非常重要的。基于PXI(PCI eXtensions for Instrumentation)平台,研发了一套基于主动Lamb波和压电传感器网络的集成多通道扫查系统,该系统结构紧凑、便于携带,能大规模自动扫查激励-传感通道并进行损伤评估。提出和讨论了该系统中:4通道PXI程控增益电荷放大器的实现、支持276个激励-传感通道的外部扫查模块和集成的结构健康监测软件的实现。最后,主要讨论了系统在某型无人机碳纤维复合材料机翼盒段上的功能验证实验,包括:压电贴层的设计、激励信号频率的选择方法、损伤成像的功能性测试、系统稳定性测试和载荷对信号的影响。实验结果验证了该系统的稳定性和损伤监测功能。
