摘要: 首先通过理论计算出温度与电磁超声换能器和待测件结构物理参数的关系，分析了温度对Lamb波在板内传播时的衰减和波速的影响，并总结出了数学模型。其次，通过有限元仿真定量分析了电磁超声换能器接收的Lamb波信号随温度的变化情况，为缺陷的准确定位和定量提供了参考依据。Abstract: Firstly, the relationship between temperature and the physical parameters of the electromagnetic acoustic transducer and the tested component structure was theoretically calculated. The influence of temperature on the attenuation and velocity of Lamb waves propagating in the plate was analyzed, and the mathematical model was summarized. Secondly, the variation of Lamb wave signals received by electromagnetic acoustic transducers with temperature was quantitatively analyzed through finite element simulation, providing a reference basis for accurate localization and quantification of defects.
