The tiny flaws such as steel inclusion sample anatomy verification.It needs that steel inclusion is accurately positioned and is identified before the dissection of defect sample, with
Just precise anatomical and micro- lookup.Since steel inclusion size is small (usually arriving several hundred microns at more than ten microns), in steel
The accurate positioning of field trash becomes the problem of Dissection test.
Currently, 08 month 2009, play arrow and guidance journal the 4th phase of volume 29, " the rodlike blank ultrasound detection side of alloy body
Method research " it mentions: using the Root cause analysis method of water immersion focusing probe detection method and C-scan mode, it is aided with automatic detection dress
It sets and automatic detection can be achieved, intuitively determine the position, shape and size of defect；Electronic measurement technique the 1st phase in 2001,
" flaw in ultrasonic testing digital imaging method and placement technology " proposes: ultrasound detection digital imaging system will directly not lack
It falls into signal and is used for defect location, first carry out echo envelope detection with Hilbert transformation, solve the inspection of noise suppressed and multimodal envelope
Survey problem, then the modeling and Power estimation analysis of AR time series are carried out, so that the envelope main peak of echo-signal is become more sharp, in band
Noise is further suppressed, and the position of defect is finally determined with finally obtained main peak envelope, and positioning accuracy is significantly better than
Traditional supersonic detector.
Above-mentioned technical proposal existing defects: special corollary equipment facility, advanced theoretical knowledge and high-tech water are needed
Flat detection operative skill, exist test limit by equipment and place, it is at high cost, program is complicated, long flow path, time-consuming, work
The deficiencies of amount is big and operating flexibility is poor, it is difficult to be promoted and applied in general enterprises, it is therefore desirable to improve.
Summary of the invention
