| 摘 要： | 本文针对传统基于时差的声发射定位方法精度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的到达时刻计算方式,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: | In this paper,a new method based on convergence algorithm is proposed to optimize the arrival time of acoustic emission signals after cyclic iteration,aiming at the problems of insufficient accuracy and stability of traditional time-based acoustic emission localization methods and the susceptibility to the detection environment.The positioning source of the reconstruction of the positioning calculation converges steadily in the same area,thus improving the positioning accuracy of the acoustic emission source. |
