Digital technologies in non-destructive testing

Abstract

This paper considers the problems of development and application of digital technologies in non-destructive testing (NDT). Conducting NDT is represented as some generalized information process. A specific object is represented in the form of digital stages: obtaining accessible, reliable and sufficient information about the properties and state of the object of testing, processing the received primary information, analyzing the processed information, making decisions about further actions with the testing object. In the paper at the system level, the formalization of an urgent and important scientific problem is proposed-the problems of developing digital technology (technologies) for each of the stages of the NDT information process. It is shown that a systematic approach to resolving a problem allows one to formulate a morphological, functional and informational description of the problem, as well as to find hypotheses for solving the problem by carrying out a sequence of operations that solve the problem. A universal structural scheme has been developed for solving scientific problems in the development of digital technologies at the stages of the NDT information process. An example of the practical application of the above approach for one of the NDT methods-functional vibro-acoustic diagnosis of objects is given.
