摘要:
材料缺陷检测的缺点是超声信号容易被系统噪声污染,本文提出超声波衍射时差法的有限元仿真方法研究材料焊缝缺陷识别,应用ANSYS软件计算有限元数字模型,确定超声检测过程仿真的加载应用规则,分析直通波、衍射波和底面回波的接收时间,得到声压幅值图像,获取实验信号,并与仿真信号比较,结果显示,采用该方法评估焊缝缺陷大小和位置是有效的。
Abstract:
Since signals may be corrupted by system noise in ultrasonic detection for material defect, we proposed to identify defects in material welding seam based on a finite element simulation of the time of flight diffraction. Our method calculated the numerical model of the finite element based on the ANSYS software. The application rules of the load were determined for the simulation of the ultrasonic detection process. The acceptance time of the received lateral, diffracted and bottom waves in the material was analyzed. The images for the sound pressure amplitudes were obtained. Results of simulated?and?experimental?signals were analyzed. We found that it is effective for the proposed method to evaluate the sizes and locations of the welding defect.
