提出了一种铝板结构健康检测的新方法，即将机磁阻抗和超声Lamb波两种技术结合起来应用于铝板结构健康检测的方法，并通过仿真研究证明了此法的可行性。超声Lamb波技术传播距离远、检测范围广、损伤定位准确，但局部灵敏度低，在对损伤程度和缺陷类型的识别上并不理想；阻抗技术检测时局部灵敏度很高，但检测范围有限、损伤定位困难。将两种方法结合起来进行结构健康检测，结合其优点，不仅可以检测出损伤的位置，还可获得损伤程度和缺陷类型等信息。同时，提出了一个融合机磁阻抗和超声导波数据的综合损伤指数，以指数的不同变化范围来对损伤程度和类型进行定性识别。

A new approach to the structural health monitoring for aluminum plate was proposed, namely a kind of approach combining magneto-mechanical impedance with guided ultrasonic wave, and its feasibility was proved by simulation research. The technology of ultrasonic Lamb wave has the advantages of far propagation distance, wide detection range and accurate damage location, but its local sensitivity is low and the identification of damage extent and type is not ideal; the sensitivity of impedance technique is very high, but the range of detection is limited and the damage is difficult to locate. Combining their advantages of the two approaches for structural health monitoring can detect all damage information. Besides, a comprehensive damage index obtained by the integration of the data of magneto-mechanical impedance and guided ultrasonic wave is proposed to qualitatively identify the damage extent and type with different varying ranges of index.
