| 摘 要： | 针对传统基于时差的声发射定位方法精度不够高及稳定性不足,且易受检测环境影响的问题,提出了一种基于收敛算法的声发射源定位方法,经过循环迭代不断优化声发射信号到达时刻的计算方式,使得定位计算重构的定位源稳定收敛在近似同一区域,从而提高声发射源的定位准确度。

| Abstract: | Aiming at the problem that the traditional time difference based acoustic emission location method has insufficient precision and stability and is easily affected by the detection environment,a new method based on convergence algorithm is proposed to optimize the arrival time of acoustic emission signals after cyclic iteration.The reconstructed source position by the positioning calculation converges steadily in the same area,thus improving the positioning accuracy of the acoustic emission source. |
