Phased array ultrasonic adaptive curve surface profiling method based on Acquire software
摘 要
介绍了利用迭代方法实现自适应曲面仿形的技术。首先通过激发相控阵超声探头的所有阵元产生平面波并接收回波;然后从回波信号中提取出渡越时间,再根据渡越时间迭代计算延时法则,将延时法则应用于探头产生下一次平面波;最后利用脉冲回波表面分析法构建被测件的表面形状。借助Acquire软件的远程控制接口,开发了客户端软件,实现了自适应仿形的功能集成。试验结果表明,该方法能够准确测量曲面构件的表面形状且运算量较小。
Abstract
This article introduces the adaptive curve surface profiling technology using iterative methods. First, by exciting all the elements of the phased array probe, a plane wave is generated and the received echo is measured. Then, the transit time from the echo signal is extracted and the delay law is iteratively calculated according to the transit time, and the delay law is applied to probe to generate the next plane wave. Finally, the pulse-echo surface analysis method is used to construct the surface shape of the test piece. With the help of the remote control interface of Acquire software, the client software was developed to realize the function integration of adaptive profiling. The experimental results show that this method can accurately measure the surface shape of curved components with less amount of calculation.
