FIELD: diagnostic technique.
SUBSTANCE: for complex analysis of informative parameters in acoustic-emission diagnostics of structures. The essence of the invention lies in the fact that the object of control is subjected to mechanical load, acoustic emission converters are installed at the control sites, with the help of which elastic mechanical waves are converted into electrical signals that are fed to an analog-to-digital converter, with which an output code is formed, then informative parameters of acoustic emission signals are calculated using special calculation blocks, the values of informative parameters are recorded and evaluated using an information display device, at the same time, the block for combining (“convolution”) informative parameters is turned on, all outputs of the calculation blocks are connected to the input of the block for combining (“convolution”) informative parameters, the output of which is connected to the information display device, and the combination (“convolution”) of the values of informative parameters is performed according to a given formula.
EFFECT: increasing the reliability and efficiency of assessing the processes of accumulation of damage and destruction of structures with periodic and constant acoustic-emission control.
