3:1
The stress distributed along a certain angle within a certain depth range on the surface of a shaft component:
Note: Commonly used detection angles are 0°, 45°, and 90°:
4 Detection Principle
According to Snel's law, in order to generate and receive ultrasonic critical refracted longitudinal waves inside the surface of the shaft component being tested, the detection probe can
The surface is placed in a direction at any angle to the axis, as shown in Figure 1a): According to the principle of acoustic elasticity, when the residual stress direction of the shaft component
When the direction is consistent with the longitudinal wave, tensile stress slows down the propagation speed of ultrasonic waves or prolongs the propagation time (t), while compressive stress speeds up the propagation speed of ultrasonic waves:
Or the propagation time (t) is shortened: If the ultrasonic propagation time (t0) in the shaft component with zero stress (σ0) is known, the ultrasonic propagation time (t0) of the shaft component under test can be calculated based on the time difference:
The residual stress (σ) in the component is calculated by formula (1):
