X-rays are widely used in the non-destructive testing(NDT)of electrical equipment.Radio frequency(RF)electron linear accelerators can generate MeV high-energy X-rays with strong penetrating ability;however,the system generally has a large scale,which is not suitable for on-site testing.Compared with the S-band(S-linac)at the same stage of beam energy,the accelerator working in the X-band(X-linac)can compress the facility scale by over 2/3 in the longitudinal direction,which is convenient for the on-site NDT of electrical equipment.To address the beam quality and design complexity simultaneously,the non-dominated sorting genetic algorithmⅡ(NSGA-Ⅱ),which is a multi-objective genetic algorithm(MOGA),was developed to optimize the cavity chain design of the X-linac.Additionally,the designs of the focusing coils,electron gun,and RF couplers,which are other key components of the X-linac,were introduced in this context.In particular,the focusing coil distributions were optimized using a genetic algorithm.Furthermore,after designing such key components,PARMELA software was adopted to perform beam dynamics calculations with the optimized accelerating fields and magnetic fields.The results show that the beam performance was obtained with a capture ratio of more than 90%,an energy spread of less than 10%,and an average energy of approximately 3 MeV.The design and simulation results indicate that the proposed NSGAⅡ-based approach is feasible for X-linac accelerator design.Furthermore,it can be generalized as a universal technique for industrial electron linear accelerators provided that specific optimization objectives and constraints are set according to different application scenarios and requirements. 展开更多

Long-duration vehicles in near space have achieved great success;however,the non-destructive testing(NDT)methods for the envelope materials of such long-duration vehicles remain blank.In this paper,we propose the air-coupled ultrasonic NDT method theoretically.In the theoretical analysis process,the envelope material is simplified as an orthogonal sandwich structure.To calculate the displacement and stress fields of each medium,the state vectors are established and the transfer matrices of the material from the upper interface to the lower interface are obtained by using boundary conditions.Then,linear equations about the amplitude of reflected and transmitted waves are derived by combining the coupling boundary conditions of air and solid.The effects of incident angles,inflation of the envelope material,and debonding of the interfaces on the transmission coefficients are considered.The results show that the air-coupled ultrasonic NDT of the envelope material can be carried out in the pre-inflated state.Finally,a method for identifying interface debonding is proposed based on judging transmission coefficients within a certain frequency range. 展开更多

Prefabricated construction represents a crucial direction for the green, industrialized, and intelligent transformation of the construction industry, and has experienced rapid development in recent years thanks to strong national policy support. Reliable connections between prefabricated components are essential for ensuring the overall performance of prefabricated structures. Among these, reinforcement sleeve grouting connections have become one of the primary connection methods in prefabricated concrete structures due to their advantages of convenient installation, reliable load-bearing capacity, and relatively low cost. The fullness and density of the grouting material within the sleeves directly determine the effective transfer of stress along the reinforcement bars, serving as a key factor in ensuring structural integrity and seismic performance. 展开更多

Pulsed eddy current （PEC） non-destructive test- ing and evaluation （NDT＆E） has been around for some time and it is still attracting extensive attention from researchers around the globe, which can be witnessed through the reports reviewed in this paper. Thanks to its richness of spectral components, various applications of this technique have been proposed and reported in the lit- erature covering both structural integrity inspection and material characterization in various industrial sectors. To support its development and for better understanding of the phenomena around the transient induced eddy currents, attempts for its modelling both analytically and numeri- cally have been made by researchers around the world. This review is an attempt to capture the state-of-the-art development and applications of PEC, especially in the last 15 years and it is not intended to be exhaustive. Future challenges and opportunities for PEC NDT＆E are also presented. 展开更多

Basic magnesium sulfate cement coral aggregate concrete(MCAC)is a new type of concrete consisting of basic magnesium sulfate cement,coarse coral aggregate,coral reef sand and seawater.The rebound hammer(RH),the ultrasonic pulse velocity(UPV)and the compressive strength(fcu)tests of 14 sets of cube specimens of the MCAC after 28 d of aging were conducted.The impact of the content and length of sisal fiber on the relationship between the fcu-RH and the fcu-UPV was determined.A mathematical model was established to predict the strength of the MCAC using the UPV,RH,and comprehensive UPV/RH methods and to obtain the curves of test strength.The applicability of the test strength curves of ordinary portland concrete(OPC),light-weight aggregate concrete(LAC),and coral aggregate concrete(CAC)to MCAC was assessed.The results showed that the test strength curves of OPC,LAC and CAC were inappropriate to determine the strength of MCAC using non-destructive method.The relative standard error of the curves of test strength of the RH method and the comprehensive method met the specifications,whereas that of the UPV method did not. 展开更多

Longitudinal joint construction quality is critical to the life of flexible pavements.Maintaining deteriorated longitudinal joints has become a challenge for many highway agencies.Improving the joint's quality through better compaction during construction can help achieve flexible pavements with longer service lives and less maintenance.Current quality control(QC)and quality assurance(QA)plans provide limited coverage.Consequently,the risk of missing areas with poor joint compaction is significant.A density profiling system(DPS)is a non-destructive alternative to conventional destructive evaluation methods.It can provide quick and continuous real-time coverage of the compaction during construction in dielectrics.The paper presents several case studies comparing various types of longitudinal joints and demonstrating the use of DPS to evaluate the joint's compaction quality.The paper shows that dielectric measurements can provide valuable insight into the ability of various construction techniques to achieve adequate levels of compaction at the longitudinal joint.The paper proposes a dielectric-based longitudinal joint quality index(LJQI)to evaluate the relative compaction of the joint during construction.It also shows that adopting DPS for assessing the compaction of longitudinal joints can minimize the risk of agencies accepting poorly constructed joints,identify locations of poor quality during construction,and achieve better-performing flexible pavements. 展开更多

Aiming at the problems of low reliability and complex operation of traditional coin-tap test of composite material,this paper introduces the grey system theory and achieves better performance.The response signals of coin-tap are classified through the grey clustering based on relation analysis,and corresponding improvements are made to the calculation method of the relation degree of nearness.First,the time history of acceleration is taken as the system behavior sequence.The improved correlation calculation method is used to solve the relation degree of nearness between the sequences,and the matrix of degree of grey relation is constructed based on this.Then,the sequence groups are summarized through the matrix,and the response signals of coin-tap are qualitatively classified according to the location of the reference sequence.Finally,the defect detection of composite materials is completed without pre-testing.The test results show that the accuracy of the coin-tap test based on improved grey clustering reaches 100%,which simplifies the operation steps while ensuring the reliability of the coin-tap test results. 展开更多

The bolt support quality of coal roadways is one of the important factors for the efficiency and security of coal production. By means of a self-developed technique and equipment of random non-destructive testing, non-destructive detection and pre-warning analysis on the quality of bolt support in deep roadways of mining districts were performed in a number of mining areas. The measured data were obtained in the detection instances of abnormal in-situ stress and support invalidation etc. The corresponding relation between axial bolt load variation and roadway surrounding rock deformation and stability was summarized in different mining service stages. Pre-warning technology of roadway surrounding rock stability is proposed based on the detection of axial bolt load. Meanwhile, pre-warning indicators of axial bolt load in different mining service stages are offered and some successful pre-warning cases are also illustrated.The research results show that the change rules of axial bolt load in different mining service stages are quite similar in different mining areas. The change of axial bolt load is in accord with the adjustment of surrounding rock stress, which can consequently reflect the deformation and stability state of roadway surrounding rock. Through the detection of axial bolt load in different sections of roadways, the status of real-time bolt support quality can be reflected; meanwhile, the rationality of bolt support design can be evaluated which provides reference for bolting parameters optimization. 展开更多

Seed vigour is an important indicator to evaluate the seed quality,and the testing of seed vigour is crucial during the growth and development of seeds.Multispectral imaging is an emerging non-destructive testing technology that has been gradually utilized in the field of seed quality testing in recent years.In this study,we used multispectral imaging to obtain image and spectral information of smooth bromegrass seeds with different maturity levels and different harvest years,and combined with five multivariate analysis methods of principal component analysis(PCA),linear discriminant analysis(LDA),support vector machine(SVM),random forest(RF)and normalized canonical discriminant analysis(nCDA)to distinguish and estimate.Results showed that LDA could predict the seed vigour of smooth bromegrass more accurately,and the accuracy of seed prediction could reach 94.2%−99.6% for different maturity levels and 90.0%−99.2% for different harvest years,which was the best differentiation model.On the prediction of seed germination,the accuracy of the LDA model in predicting normal seedlings of smooth bromegrass seeds in different harvest years(93.6%)was higher than different maturity levels(66.7%).The prediction accuracy of nCDA could reach 93.7% and 91.3% for dead seeds with different maturity levels and different harvest years,and 91.1% and 91.3%for high vigour seeds,respectively.The above results confirmed the feasibility of the multispectral imaging techniques combined with the multivariate analysis methods for rapid and non-destructive differentiation of seed vigour of smooth bromegrass,and it also showed good application prospects in the seed vigour testing field. 展开更多

Bridges are important elements in road system and can influence the entire economy of cities and region. Usually, these structures have high financial investments for their constructions, in this way, maintenance and conservation become so important. Inspection is a technical activity that covers several operations, including performance analysis; examination; final performance report, other operations may be necessary, such as maintenance work, recovery, strengthening and rehabilitation. Technical examination together with some test methods allows a critical and parametric judgment of the bridge performance by minimizing the subjectivity of visual evaluations, and permits a more detailed diagnosis. This paper discusses the methodology to perform tests to complement the assessment recommended by DNIT （Brazilian National Department of Transport Infrastructure）, which consists only on a visual judgment. This approach provides technical basis to classify the bridges as its need and urgency of maintenance. 展开更多
