摘要
A probabilistic model for estimating the error in determining the coordinates of acoustic emission (AE) sources based on experimental data is considered. A spherical indentor was pressed in a test object to obtain a large number of AE signals. Processing of signal parameters has made it possible to reveal the dependence of the likelihood of determining the coordinate with a prescribed accuracy on the maximum amplitude and AE-signal rise time. The possibility for choosing the method of detection of the AE-signal time of arrival at receivers depending on the signal parameters has also been examined.
