Attached power size, is widely used in the fixed network of sensor in Ultrasonic NDT.
Background technology：
Residual stress is a major criterion of workpiece quality assessment, has very big harm to the workpiece of military service, for example, plus
The generation of fast fatigue crack, reduces fatigue life, occurs stress corrosion, deformation, unstability etc., thus to the Clinical significance of detecting of material compared with
Greatly.There is the defects of damaging equipment and larger error in current most widely used Strain Method and Blind Hole Method, and device is larger is not easy
Carry, be not easy to measure.
Ultrasonic wave tests residual stress using Sound elasticity principle, and Sound elasticity principle refers to the spread speed of ultrasonic wave
Linear relationship is presented with the stress in workpiece.Indulged at present using more, more mature ultrasonic test waveform for critical refraction
Ripple, critical refraction longitudinal wave are compressional waves with special pattern caused by first critical angle incidence, are passed parallel to the surface of workpiece for measurement
Broadcast.The distance between fixed transmitting-receiving probe, can then test out according to the change in critical refraction longitudinal wave propagation time in workpiece
The state of residual stress in workpiece.
In traditional stress mornitoring field, residual stress is detected usually based on plane, and dress is detected to the residual stress of curved surface
Put research and development to be short of, especially in terms of the definite and device fixation at the first critical refraction angle.
From Sound elasticity principle, the incidence angle of ultrasonic wave need to ensure the first critical refraction angle.In plane monitoring-network, surpass
Sound wave transmitting-receiving probe is fixed on two opposite inclined planes of an organic glass voussoir, and test zone is fixed, and relative to treating
The angle of inclination for surveying workpiece surface is fixed.This inclination angle fixed is the first critical folding tested and calculated based on workpiece material
Firing angle.And there are many curve surface work pieces in actually measuring, due to the inclined plane of planar detecting device fix and device in itself without
Method is adjusted so that and it can not ensure that ultrasonic wave is incident according to the first critical refraction angle when measuring quadric stress, cause very big error,
Even mistake.And since the curvature of curved surface is different, if fixing device only adapts to a kind of curvature and significant wastage must be caused superfluous with equipment
Miscellaneous, so being detected for quadric stress, device be able to must be adjusted accurately according to different curvature, can accurately just make ultrasound
