In this paper, a new ultrasonic array inspection method, the Full Matrix Capture (FMC) and Total Focus Method (TFM) algorithm, has been studied and applied to the high speed railway wheel inspection, especially in the wheel web from the tread. The Total Focusing Method (TFM) which processing image with the data set captured by the approach of Full Matrix Capture (FMC) has been adopted in the field of industrial non-destructive evaluation from medical field since 2005. In this paper, the model is introduced to discuss the principle of FMC and the signal processing method of Hilbert transform which to solve the analytic signal to recover the instantaneous phase information for high resolution imaging. Then the TFM as the reconstruction algorithm is discussed and simulated with different size of aperture to evaluate the performance of TFM. The experiments on the PA block and railway wheel are carried out based on the conventional Phased Array (PA) and FMC method. The inspection result, such as the reliable detection, SNR and image resolution, has been analyzed and discussed according to the different active aperture size based the TFM algorithm, comparison to the conventional phased array UT. It is demonstrated that this TFM algorithm is with good potential for the wheel inspection.","PeriodicalId":413995,"journal":{"name":"2013 Far East Forum on Nondestructive Evaluation/Testing: New Technology and Application","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121655949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulations are carried out by using AC/DC module of COMSOL mul-tiphysics software.

The accuracy of time-delay estimation (TDE) directly influences the precision and reliability of the relative measurement method used in non-destructive testing, such as leak location in underground pipeline leak test, ultrasonic blood velocity measurement, ultrasonic material stress measurement etc. In this paper, methods based on third-order cumulant are applied, including Cross Third-order Cumulant Method and Bispectrum Method, to ultrasonic time delay estimation. Higher-order cumulant can effectively suppress big noise interference. According to the principle that the third moment sequence of a zero-mean Gaussian process is identical to zero, we can use third-order cumulant to estimate time delay. Comparing with Generalized Cross-correlation Method, these methods can suppress the effect of correlated Gaussian noise sources and can be used as the substitution of Generalized Cross-correlation Method.","PeriodicalId":413995,"journal":{"name":"2013 Far East Forum on Nondestructive Evaluation/Testing: New Technology and Application","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131307872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One is to apply a high frequency approximation for transmitted waves through curved interfaces to improve SAFT images of flaws in a structure with complex geometry. As examples, the improved SAFT is applied to pitch-catch data for flaws in an immersed round bar, and flaw images are compared with conventional SAFT images. Another application is to use a low frequency approximation to reconstruct a flaw shape of 3-D plate thinning from reflection coefficients of ultrasonic guided waves. By introducing a far field expression of Green's functions and Born approximation into the integral expression, a Fourier transform pair is obtained between the shape function of thinning flaw and reflection coefficients of backscattered guided waves. Some numerical examples are illustrated to show the validity and effectiveness of our inverse approach.","PeriodicalId":413995,"journal":{"name":"2013 Far East Forum on Nondestructive Evaluation/Testing: New Technology and Application","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125202404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
