摘要Abstract
Long-distance, large-areadetection and monitoring techniques are of great importance in modernindustries. The phased array system based on omnidirectional shear-horizontal(SH) wave transducers can realize quick scan on large plate-like structures.However, currently there are no SH wave piezoelectric transducer available. Inthis work, we proposed an omnidirectional SH wave piezoelectric transducer(OSH-PT) based on a thickness-poled piezoelectric ring on which the electric fieldis circumferentially applied, resulting in the thickness-shear (d15) mode. Boththe theoretical analysis and experimental testing indicate that this OSH-PT canexcite single-mode SH0 wave in a wide frequency range and it shows nearlyuniform sensitivity along all directions. The proposed OSH-PT may change thesituation of the guided wave based inspection technique for plate-likestructures.

摘要Abstract
It was possible that theinspector would miss the defect entirely that lay underneath support platebecause of the interference of the support plate signals. Analyzing thesuperposition characteristics of the defect signals closing to the supportplate, a research is carried out about the influence of the support plate onthe eddy current testing of the ferromagnetic materials. The result shows thatthe defect signal will overlap the plate signal when the distance between thedefect and the support plate is less than 10mm. Meantime there is a defect lobe appearing on the left side of the plate;when more than half of the support plate is covered defects signal, it will becomealmost completely engulfed by the plate signal. Moreover the plate signalbecomes bulky. Trough defects have a bigger influence on the electromagneticwave. Its volume affects the amplitude of the defect signal. The greater thevolume is, the larger the amplitude becomes .

摘要Abstract
In order to realize the on-line monitoring of coupling state in phasedarray ultrasonic testing, a support vector machine classification method basedon Gaussian kernel function was proposed, which improves the accuracy ofcoupling state evaluation effectively. The method mapped the original sample toanother feature space by nonlinear transformation, and constructed a separatehyperplane in this feature space to classify the samples accurately. On thebasis of this, the support vector classifier based on the Gaussian kernelfunction was constructed according to the training samples, and the testsamples were tested with the test samples. It can be seen from the results thatthe accuracy of the coupling state is up to ( ), and the on-line monitoring ofcoupling state is realized effectively.

摘要Abstract
Eddy current (EC) testingis a conventional nondestructive method, for inspecting conductive material withoutdirect contact and is widely used in many fields such as aerospace. In thismethod, the speed of EC attenuation is of great concern and is quantified byskin depth. The skin depth is usually calculated in the scenario that the testsample is of infinite thickness. In many applications, however, the thicknessof test sample is finite. This paper investigates the law of attenuation of ECexcited by pancake coil inside flat plates of finite thickness using the finiteelement method. Simulation results show that the attenuation of EC in monolayerplate of finite thickness is slower than that in conductive half space. Incompound plate, there is a jump of EC density on the interface of the upperpart and lower part of the plate. In multilayer plates, the air gap betweenadjacent layers slightly reduces the speed of EC attenuation in the upper layerand makes the amplitude of EC density in the lower layer smaller. The phenomenaare explained from physical point of view in the paper.

摘要Abstract
Eddy current testing(ECT) is known as an effective technology for inspecting surface and nearsurface defects in metallic components. It is well known that the amplitude ofeddy current (EC) decreases with increasing depth, which is referred to as skineffect. Skin depth is an important parameter that quantifies the speed ofattenuation of EC in the depth direction and is closely related to thecapability of ECT for detecting deeply hidden defects. It is found that thetraditional formula for calculating skin depth is not applicable for the casesof ECT with coils. The skin effect of EC in component with flat surface excitedby pancake coil has been investigated by the authors. The skin effect of EC incylindrical component excited by bobbin coil or encircling coil is morecomplex. This paper studies the skin effect of EC associated with these twotypes of coils. Finite element analysis shows that the attenuation of EC is notonly due to the loss of EC, but also influenced by the diffusion effect,aggregation effect, and the combined cancellation/diffusion effect of EC. Theskin depth of EC associated with bobbin coil is always smaller than thatassociated with uniform plane field excitation, whereas the skin depth of ECassociated with encircling coil can be greater than that associated withuniform plane field excitation under certain conditions.

摘要Abstract
       The support vector machine can avoid the learning phenomenonin the case of small training samples, so that the generalization ability canbe maximized. In this paper, we support the problem that the SVM parameterscannot be selected adaptively. By using the global search characteristic of thegenetic algorithm, the parameters of the support vector machine are optimizedand the optimal parameters of the support vector machine are obtained. Thismethod is used to study the acoustic emission detection of gear fault, and theexperimental system is composed of PCI-2 acoustic emission system and rotarymachinery vibration fault simulation test bed. The accuracy of faultclassification is 10% higher than that before optimization, which is veryimportant for gear fault diagnosis.

摘要Abstract
       Ultrasonic testing equipment combined probe modulated pulsesgenerated on the defect resolution, not only affects the defect quantitatively,and influence the detection rate of defects, and the factors determining thepulse modulation by equipment trigger pulse frequency, probe nominal frequencydecision. It is possible that the center frequency of the pulse of the defectreflected wave is much different from that of the probe. If the center frequencyof the defect reflection pulse is not within the -6dB bandwidth of thetransmitting frequency, it will mean the defect detection. Therefore, byimproving the equipment combination probe to improve the pulse bandwidth, thedefect resolution, the device remains unchanged, will need to probe differentfrequency changing to achieve the best combination of pulse modulation, to meetthe requirements of ASME rules requirements, to meet the requirements of aspecific defect detection rate of workpiece.

摘要Abstract
Electron beam welding(abbr: EBW) is widely used in CRGT, and the depth of fusion is the priority tobe considered when judging the welds quality. The major problem here is thatthe distance between folding edge and the weld is close so regular angularsensor can hardly be used; Meanwhile, because of the tiny special dimensionaround the edge, when using the normal probe, avoiding the near area andensuring the beam vertical incidence are also difficult. This research,however, firmly combined the ultarsonic testing theory and the engineeringpractice, introducing immersed method to address the problems above. The methodis proved to be efficient and effective, and can be popularized in thethird-generation nuclear power thchnology like AP1000 and Hualong One as well.

In this study, we took metal plate specimens with differentsizes of fatigue cracks as objects, obtained the thermal response signals ofdifferent sizes of crack specimens through orthogonal experimental design; Thenestablished the relationship between thermal response signals and crack sizesby using the linear regression model, and gave the specific parameters in thecrack detection probability model by using the maximum likelihood estimationmethod; Finally, obtained the confidence interval of detection probabilitybased on Wald method. The research aims to provide a quantitative evaluationmethod for detection reliability in pulsed eddy current thermography.

摘要Abstract
Long-distance inspectionand monitoring of pipelines is of great importance in modern industries. Thecurrently used longitudinal wave suffered from limited inspection distance forburied pipelines. In comparison, the non-dispersive torsional wave T(0,1) ismore promising. In this work, we proposed a torsional wave transducer based onface-shear (d24) piezoelectric ring. Both theoretical analysis and experimentaltesting indicated that using 24 elements, this transducer can completelysuppress the flexural wave modes, and excite and receive the single-modetorsional wave T(0,1). The proposed torsional wave transducer is especiallysuitable for long-distance monitoring of buried pipelines due to its simpleassembly, low cost and low power.

摘要Abstract
As the increase ofrailway speed, the impact of wheel roundness on running safety and comfortbecomes greater. Under high speed operation, the effect of high order wheelroundness dramatically decreases the life time of car components and tracksystem. An on-board wheel roundness monitoring technique was proposed in thispaper. The vibration signal from the acceleration transducer installed on theaxle box was processed to get the wheel roundness order. This method is provento be valid with on-board experiments and real findings. At last, therelationship between train speed and vibration strength at different roundnesslevel is also discussed.

摘要Abstract
The progression characterisationof exposed atmospheric corrosion on metal substrates is a major problem in the?eld of corrosion science and Non-destructive evaluation (NDE). High frequencyradio frequency identification (HF RFID) sensors are attractive in diverseapplications where sensor performance is needed at a low cost and dimensionrestriction. An approach adapting commercial passive 13.56MHz RFID tags forsensing corrosion stage has been developed. The investigation includes balanceof sensing and positioning of RFID sensors for corrosion detection by analysingreal part and imaginary part of the complex impedance. With passive RFIDsensors, real part and imaginary part of complex impedance are extracted fromthe reader coil with Vector network analyser (VNA) and delivering a unique capabilityfor corrosion sensing with different atmospheric exposure time steel samples (1month, 6 months, 10 months and 12 months). The relationship between thesefeatures and corrosion exposed time has been derived which is useful forcorrosion progression measurement, early stage corrosion monitoring andprediction in industrial fields such as the marine industry.

摘要Abstract
This paper will describethe experience of inspecting steam generator tubing by applying a single passprobe that contains alternative sensor configurations utilizing independentexamination techniques where analysis is performed by automated analysissoftware. The dual pass probe contains a traditional bobbin sensor plus anarray sensor set, providing alternate techniques and alternate analysis methodsin examining the steam generator tubing. This approach provides independence andconfirmation on a single pass examination of tubing. The single pass providesbenefits in fewer man hours for the examination, lower dose received, andreduced radiation waste compared with the traditional approach where theexamination is performed using a primary examination technique for the majorityof the inspection scope followed by a second probe insertion to perform asecondary examination technique for special areas of interest or confirmationof the primary technique. In addition to the savings in man hours andaccumulated dose, further benefits are realized through the application of dualtechniques through the examination scope providing a more comprehensiveexamination of the steam generator tubing. Automated analysis is used toleverage the results between the two independent techniques to provide moreresolved answer and perform analysis at a production rate to keep pace with theacquisition of data.

摘要Abstract
Tensile and compressiveexperiments of demagnetized specimens made of Q235 steel were conducted, andmagnetic signal variation characteristics under different tensile andcompressive stresses were recorded continuously using magnetic memory on-linemonitoring system. The results show that the resultant magnetic field decreasesfirstly and then increases induced by tensile load, and tends to be stable whenapproaching and exceeding 0.3 times the yielding strength of the material,whist the resultant magnetic field induced by compressive stress declinequickly in the initial stage, and then tends to fluctuate. The J-Amagnetomechanical effect model is improved by introducing different stressdemagnetization terms caused by tensile and compressive stresses, and the simulationresults are in good agreement with the experimental data, which can be used fortheoretically explaining different mechanism induced by tensile and compressivestresses.

摘要Abstract
       In this paper, small cracks (depth < 1 mm) initiated fromtop surface of welded butt joints are imaged and characterized using ultrasonicarray. The conventional Total Focusing Method (TFM), which allows the array tobe focused at every point in the target region in both transmission andreception, is a post-processing imaging algorithm of ultrasonic array data.However, it is challenge to size the small cracks initiated from top surfaceusing conventional Total Focusing Method, because no reflection from crackfaces nor root/tip indications is observed in the image. The reason is that theconventional Total Focusing Method imaging algorithm includes only direct raypaths between the array and image points, and only very little wave enginereaches to the small cracks near the top surface where the array located. Thispaper presents four modes of wave propagation combined into the Total FocusingMethod imaging algorithm to inspect and image the small cracks. This post-processingtechnique shows great reliability to measure the depth of the small.

摘要Abstract
       Signal-to-noise ratio (SNR) is one of the key parameters indigital radiography (DR), thus we should pay more attention on it. Somequestions were analyzed and discussed, which include the meaning of SNR in DRand the purpose of normalization of SNR and the relationship between SNR andcompensation principles (CP). After theory analysis, we know the detectabilityof flaws in DR is closely related with the SNR parameter in general. So,increased SNR can compensate reduced contrast from higher x-ray energy in DR,which is called CP I. Contrast in the testing result of film radiography and DRis both the product of a certain factor and the mainsubject contrast, and thefactor in DR using flat panel detector is SNR, while that in film radiographyis related with gradient-to-noise ratio. Film system in radiography testing canbe classified according to the SNR parameters (gradient-to-noise ratio), andcomputed radiography (CR) system can be classified by SNR parameter likewise.With the help of normalized SNR, the image quality in DR and film radiographycan be measured and evaluated equivalently. DR technique suffers from inherentdetector unsharpnessat present, but the unshrpness can be compensated byincreased SNR, which is called CP II. This compensation principleseems to haverelation with requirement of normalized SNR, but we should know that basicspatial resolution of a digital detector and the measured unsharpnessin thetesting are different. Besides, this compensation principle affected by manyfactors and it should be adopted with care. In the practical testing, we shouldknow the properties of the detector used and the requirement of detection ofcertain flawsthusensure that applicableprocess is adopted consequently.

摘要Abstract
       In some mainly shear wave electromagnetic acoustic transducers(EMATs) such as spiral coil EMATs, an existing longitudinal wave distorts theshear wave response and complicates the echo pattern. In order to enhance shearwave purity, the effects of an impedance matching network and a band-passfilter on the bulk wave amplitudes in the ultrasonic receiving system wereinvestigated by experiments. Subsequently, the influences of magnet dimensionsand the thickness of Si-steel backplate on shear wave purity were also studied.Results indicate that a band-pass filter and an impedance matching networkdesigned at a center frequency that is the same as the excitation current, alarger diameter and smaller thickness magnet, and a thicker Si-steel back-platecan help to improve the shear wave purity, but it is at some sacrifice of the shearwave sensitivity.
