The invention discloses a plane wedge ultrasonic surface wave probe performance parameter determination method and system, and belongs to the technical field of ultrasonic detection. After a plane wedge block ultrasonic surface wave probe is fixed through a first clamp and a second clamp, relative horizontal movement of the plane wedge block ultrasonic surface wave probe can be achieved through a translation mechanism, after the position is adjusted, two plane wedge block ultrasonic surface wave probes can be locked through the locking device for follow-up related operation, and it is avoided that the measurement result is affected by position change. According to the method, the related parameters of the probe can be obtained by adopting the two planar wedge ultrasonic surface wave probes with the same performance parameters under the condition that a test block is not needed. The method is simple and convenient to operate, does not depend on the experience and skill level of an operator, and has good applicability; and the determination result is accurate, a corresponding test block does not need to be prepared according to the model of the probe, the acquisition cost of the test block is reduced, and the adaptability is good.
Description
technical field [0001] The invention belongs to the technical field of ultrasonic testing, in particular to a method and device for measuring performance parameters of a planar wedge ultrasonic surface wave probe. Background technique [0002] When the surface of the medium is subjected to alternating stress, a wave propagating along the surface of the medium is generated, which is called ultrasonic surface wave. The composite vibration track of solid surface particles produced by ultrasonic surface waves is an ellipse around its equilibrium position. The long axis of the ellipse is perpendicular to the wave propagation direction, and the short axis is parallel to the wave propagation direction. The size of the particle amplitude is related to the elasticity of the material and the penetration depth of the ultrasonic surface wave, and its vibration energy decreases rapidly as the depth increases. When the penetration depth of the ultrasonic surface wave is close to one wave...
