Abstract

Abstract: Ultrasonic stress measurement technology is a kind of stress nondestructive testing technology based on measuring the change of sound speed, which has the advantages of simplicity, rapidity and wide applicability, etc. However, in the actual measurement process, the measurement results are easily affected by the environmental factors at the measurement site, the measurement personnel and the measurement process, which leads to the low repeatability of the measurement. This paper proposes a high repeatability control method that takes into account the influencing factors at the measurement site. By analyzing the principle of stress measurement and the measurement process, it is clear that the mutual relation step size, the interface coupling strength and the ambient temperature are the key factors affecting the stability of the measurement; the test analyzes the influence of the three on the measurement results, and puts forward the method of controlling the interface coupling strength, the method of temperature compensation, as well as the method of selecting the optimal mutual relation step size, and ultimately, the ultrasonic stress measurement software is formed through the integration and development of LabVIEW. Through the mechanical tensile experiment combined with the stress measurement experiment, the maximum deviation of the error control compensation module is 2.9 MPa, and the maximum uncertainty is 2.4 MPa, which is 91% lower than the maximum deviation of the traditional measurement method, and 81% lower than the repeated measurement error, which verifies that the proposed method can significantly improve the repeatability and accuracy of ultrasonic stress measurement. The stress measurement accuracy control method and software proposed in this paper can significantly improve the repeatability and accuracy of ultrasonic stress measurement, can reduce the requirement for the proficiency of the measurement personnel without increasing the cost of measurement, and has high value for engineering applications.

Key words: ultrasonic stress measurement, interfacial coupling strength, temperature, intercorrelation step size, repeat measurement accuracy
