Stress measurement method, device, equipment and storage medium for metal components

Abstract

The invention discloses a method for measuring the stress of a metal component, which includes heating the metal component to be tested and collecting an infrared thermal image of the metal component to be measured and a heating time corresponding to the infrared thermal image; according to a predetermined deep neural network model, the infrared thermal image And the heating time determines the current stress of the metal component to be tested; the deep neural network model is a model of the relationship between the infrared thermal image of the metal component corresponding to the specific heating time and the stress. In this application, based on the fact that when the metal component to be tested is subjected to stress, the local electrical conductivity will change, and the temperature is also different. Combining deep learning with infrared thermal imaging can improve the accuracy and accuracy of the stress detection of the metal component. Efficiency, saving time and cost, is conducive to the effective evaluation of the working status of metal workpieces. The present application also provides a stress measuring device, equipment, and computer-readable storage medium for metal components, which have the above-mentioned advantageous effects.
