本文详细研究了线性定位法对偏离换能器连线的声信号的定位精度 ,在此基础上 ,提出了一种既适合于声换能器连线上声信号的定位 ,又适合于偏离声换能器连线并平行于声换能器连线上声信号的线性定位新方法 ,即声发射信号的广义线性定位法。用Hsu -Nielsen声源在平面钢板上进行了的定位试验 ,证明广义线性定位法比线性定位法具有更高的定位精度及更广泛的适用性
In this paper, the localization accuracy of linear positioning method for acoustic signals deviating from the transducer connection is studied in detail. Based on the above, a new acoustic localization method is proposed which is not only suitable for acoustic signals on the connection of acoustic transducers, A new method of linear positioning of the transducers connected to and parallel to the acoustic signals on the acoustic transducer connections is the generalized linear positioning method of acoustic emission signals. Positioning tests conducted on a flat steel plate with Hsu-Nielsen sound source have proved that the generalized linear positioning method has higher positioning accuracy and wider applicability than the linear positioning method
