摘要
针对橡胶材料与金属板粘接样件厚度及粘接质量,采用反射式太赫兹时域光谱(THz-TDS)系统对其进行无损检测。通过对检测数据中各点时域波形飞行时间信息的分析,得到样件橡胶部分的二维厚度分布图,实现了橡胶样件厚度分布的可视化成像;通过对检测数据中特征点波形及B-Scan图像的综合分析,判断出样件的分层缺陷。该研究结果为橡胶材料厚度及分层缺陷的无损检测提供了有效的解决办法。
Based on the thickness and bonding quality of rubber materials and metal plate bonding sample, nondestructive testing was performed by using reflective Terahertz Time-Domain Spectroscopy (THz-TDS) system. Through the analysis of the flight time information of the time-domain waveform of each point in the testing data, the two-dimensional thickness distribution of the rubber part of the sample was plotted, which realized visualization of thickness distribution information. Through the comprehensive analysis of the characteristic point waveform and the B-scan image in the testing data, the delamination defects of the sample were determined. This study provides an effective solution for nondestructive testing of rubber materials thickness and delamination defects.
