Abstract

A new simple experimental scheme for two-dimensional planar location problem of acoustic emission technology is proposed.New triangle time difference algorithm is adopted to realize sound source localization and GPS simulation of two - dimensional plate by using simple experimental method at the same timewith only two ultrasonic sensors to complete the experiment.This new method simplifies the experimental equipment,reduces the cost,is suitable for popularization with simple calculation process,and also helps us to have an insight into the physical problem of the acoustic emission technology.
