基于兰姆波的诊断图像法直观地展现了结构的健康状况。该文通过损伤参数(位置、形状、方向、严重程度)与兰姆波信号特征(飞行时间,信号强度)的联系,研究开发了一种新颖的诊断图像法,并基于传感器网络对结构健康状况进行监测。采用有限元仿真与实验研究两种手段对有裂纹的铝板进行诊断。其成像结果具有较高的精度,证明了本方法的可行性。 The diagnostic imaging method based on Lamb waves shows the structural health status intuitively. In this paper, a new diagnostic imaging method is developed based on the relationship between the damage parameters (position, shape, direction and severity) and Lamb wave signal characteristics (flight time, signal intensity). Based on the relationship between the structure health status Monitoring. Finite element simulation and experimental study of two methods to crack the aluminum plate for diagnosis. The imaging results have higher accuracy, which proves the feasibility of this method.
