摘要:
为解决当前传统超声检测技术对复合材料的检测耦合剂污染和检测效率低等问题,提出空气耦合超声共振法来检测复合材料薄板的厚度,从而确定缺陷的大小。利用 COMSOL 有限元仿真软件对复合材料进行建模,设置不同厚度及不同大小缺陷的物理模型来对比实验,后处理求解并进行快速傅里叶变换,提取谐振频率计算出复合材料的厚度。结果表明,超声共振法可对复合材料进行定性、定量检测;当复合材料的厚度越薄时,超声信号产生的谐振频率越大,则复合材料中所含缺陷范围越广,分层现象越严重;其检测精度可达 0.1 mm 左右,相对误差范围分布在 5% 以下。实验证明了该测厚技术的可靠性,为超薄复合材料板缺陷厚度的测量提供一定的参考和借鉴。
Abstract:
In order to solve the problems of coupling agent pollution and low detection efficiency of traditional ultrasonic testing technology for composite materials , an air-coupled ultrasonic resonance method is proposed to detect the thickness of composite sheet , so as to determine the size of defects.The COMSOL finite element simulation software was used to model the composite material , and the physical models with different thicknesses and different sizes of defects were set to compare the experiments results.The post processing solution was carried out and the fast Fourier transform was performed to extract the resonant frequency to calculate the thickness of the composite material.The results show that the ultrasonic resonance method can qualitatively and quantitatively detect thecomposite plate.And when the thickness of the composite is thinner , the resonant frequency generated by the ultrasonic signal is larger , the defect range of the composite is wider , and the delamination is more serious.The detection accuracy can reach about 0.1 mm , and the relative error rate is below 5%.The experiment proves the reliability of the thickness measurement technology , which provides certain reference for measuring the defect thickness of ultra-thin composite plate.
