Foil gauge method of testing, photorefraetive crystal, mistor sensor method and ultrasonic wave stress mornitoring method.
Ultrasonic wave stress mornitoring method as the novel stress mornitoring method developed rapidly in recent years, because its have to human body without
Evil, feature not damaged to measured object, measuring speed is fast, are applied in more and more industrial occasions.It is visited using ultrasonic wave
Head to bolt stress detect when, since the acoustic characteristic impedance of air and engineering material differs greatly, for avoid ultrasonic probe with
There are the air gaps between threaded bolt contacts face, prevent ultrasonic energy from being efficiently entering bolt, generally need to be in ultrasound in practical application
Daubing coupling agent between wave probe and threaded bolt contacts face.In actual operation, survey crew is usually in ultrasonic probe and bolt
Between contact surface after daubing coupling agent, ultrasonic probe is adjacent to threaded bolt contacts face manually, but between ultrasonic probe and bolt
The tightness degree of coupling also largely influences the accuracy of ultrasound examination bolt stress, manual compression ultrasonic probe
Operation on the one hand not can guarantee largely ultrasonic probe measurement consistency, on the other hand also draw to test macro
Accidental error is entered.
Summary of the invention
