曲面和三维结构的声发射源定位方法
LOCATION OF ACOUSTIC EMISSION SOURCE ON CURVED SURFACES AND THREE-DIMENSION STRUCTURES
【摘要】 曲面和三维结构的声发射源定位方法主要有时差定位法、区域定位法、相关关系定位法和模式识别定位法。详细介绍曲面和三维结构的时差声发射定位方法。
【Abstract】 There are mainly four methods for locating acoustic emission sources on curved surface and three dimension structures including time arriving, zone, correlation and pattern recognition. Time arriving method is introduced in detail.
