Ultrasonic testing of transverse shear force in bolt

The principle of bolt axial stress detection is introduced, a shear fixture is designed, and the linear relationship between shear force and time delay under different torques is studied by ultrasonic detection method. The results show that there is a linear relationship between shear and time delay under different torques, but the slope is different, which can provide a basis for measuring bolt shear stress by ultrasonic method.
