In-situ nondestructive testing method for testing bearing capacity of equipment during destructive collision

Abstract

For the situation that nondestructive testing and destructive collision, belong to two deformation levels which are completely different in magnitude and property, currents of mathematical / mechanicaltheories for revealing the mapping relationship between the two layers are not proposed yet so far, the invention provides an in-situ nondestructive testing method for detecting the bearing capacity of equipment during destructive collision based on artificial intelligence, which is characterized in that a special connection mechanism is established between two deformation levels with completely different magnitudes and properties, namely nondestructive testing and destructive collision, by virtue of the artificial intelligence. That is to say, based on machine learning theory, an artificial intelligence bridge (AI model) is erected between the characteristic parameters of the equipment and the bearing capacity of the equipment during destructive collision , characteristic parameters of the equipment are obtained based on nondestructive testing methods such as a structural power identification method, the bearing capacity of the equipment during destructive collision is obtained with the help of the AI model, and in-situ nondestructive testing of the bearing capacity of the equipment during destructive collision is achieved. Compared with the prior art, the technical scheme provided by the invention has the beneficial effect that the in-situ nondestructive testing of the equipment bearing capacity under the destructive collision condition is realized by utilizing a nondestructive testing method.
