基于单激发端多接收端压电阵列的板内损伤检测
Damage Detection for a Plate Based on a Single-transmitter Multi-receiver PZT Array
摘要
Abstract
Based on ultrasonic guided wave technique ,the damage detection for plates was studied . The characteristics of Lamb wave propagation were discussed herein .With the help of finite element coupling field simulation ,the wave propagation and wave interaction with crack damage of Lamb waves were simulated .From the simulation results ,the affection of crack size on Lamb wave propaga‐tion was analyzed .In order to quantify the locations and sizes of the damages ,a single-transmitter multi-receiver PZT array was employed .Combined with probability-based imaging method ,the dam‐age distribution of the plate could be obtained .The imaging results of this distribution can reflect the location and severity of the damage obviously .关键词
