Description
Technical field
The utility model relates to the fixing device of acoustic emission testing instrument signal acquisition probe, in particular to a kind of fixing device for fixing this signal acquisition probe.
Background technique
In material, regional area produces a kind of elastic stress wave of transient state owing to discharging strain energy fast, can be called that stress wave is launched.It is a kind of common physical phenomenon, and the acoustic emission signal frequency of different materials is also different.General acoustic emission signal frequency is from being divided into: infra-acoustic frequency, audio frequency and ultrasonic frequency.Frequency range is very large from a few Hz to MHz, and signal amplitude is large, can 1m magnitude from the 10-13m of the dislocation motion of microcosmic to seismic waves, if when strain energy acquires a certain degree, the acoustic emission signal of generation just can allow people's ear hear.Generally, the acoustic emission signal intensity that most of material deformation and fracture produce is very faint, and we can not hear by people's ear, in this case, will detect by some highly sensitive electronic equipments.Acoustic emission signal is by instrument detection, record and analyze and judge acoustic emission source and the method evaluating the mobility defect of tested object is called acoustic emission technique.
