| 520 | 3 | |a Acoustic emission (AE) source localization is a fundamental element of rock fracture damage imaging. To improve the efficiency and accuracy of AE source localization, this paper proposes a joint method comprising a three-dimensional (3D) AE source localization simplex method and grid search scanning. Using the concept of the geometry of simplexes, tetrahedral iterations were first conducted to narrow down the suspected source region. This is followed by a process of meshing the region and node searching to scan for optimal solutions, until the source location is determined. The resulting algorithm was tested using the artificial excitation source localization and uniaxial compression tests, after which the localization results were compared with the simplex and exhaustive methods. The results revealed that the localization obtained using the proposed method is more stable and can be effectively avoided compared with the simplex localization method. Furthermore, compared with the global scanning method, the proposed method is more efficient, with an average time of 10%–20% of the global scanning localization algorithm. Thus, the proposed algorithm is of great significance for laboratory research focused on locating rupture damages sustained by large-sized rock masses or test blocks. | |
