Ultrasonic quality control of press-fit joints
Source abstract
Abstract
A technique for quantitatively evaluating the quality of interference-fit joints by the echopulse method is proposed. A formula is obtained for calculating the value of the coefficient of ultrasound reflection from the site of the joint fit from the measured amplitudes of echo pulses in a free ring and in an assembled joint. It is shown that the reflection coefficient is the main parameter characterizing the quality of an interference-fit joint, i.e., its ability to withstand loads, determined by the maximum value of the torque transferred by a pressure joint, because the reflection coefficient is related to the normal stresses at the contacting surfaces of the joint. To optimize the process of studying the quality of a joint, it is noted that the automation of the testing procedure using the proposed technique is possible and desirable.
