摘要 ：

针对重大基础设施安全运行需要,本文进行了金属板结构疲劳损伤非线性兰姆波检测方法研究.基于兰姆波二次谐波产生条件,确定了产生二次谐波积累增长效应的两种兰姆波模态及对应的激励频率.通过有限元仿真,研究了材料性能改变对兰姆波非线性效应的影响,证明了二倍频兰姆波非线性系数对材料性能退化表征的有效性.在此基础上,开展了金属板结构疲劳损伤非线性兰姆波检测实验研究.将极性反转方法应用于疲劳试件检测实验中,有效提高了检测信号中二倍频兰姆波的幅值和信噪比.实验结果表明,两种兰姆波模态对的二次谐波非线性系数均随疲劳损伤增加呈线性增长趋势,但基频S(0,2)模态和二倍频S(0,4)模态对对疲劳损伤检测的灵敏度更高,更适合金属板结构疲劳损伤检测.

摘要 ：

Aiming at quantitative identification of defects in structures, the scattering characteristics of defects in structures are studied. The scattering simulation model of elliptic defect is established and the effect of defect deflection angle and size on the de-correlation of scattering signal is studied. The results show that the de-correlation coefficient matrix of ultrasonic signal has a great correlation with the defect geometry state (such as size and angle), but it is not a simple linear correlation. On this basis, combining the parametric finite element analysis and Bayesian theory, a defect inversion method based on ultrasonic scattering signal de-correlation analysis is developed, and the numerical simulation and detection experiments of defect inversion are carried out. The results show that the developed defect inversion method can well realize the inversion of the position and size of defect in aluminum block and plate. The inversion error of the open defect size (depth) of the aluminum block is about 0.2 times of the excitation wavelength, and the position error is about 0.6 times of the excitation wavelength. The inversion error of the circular defect size of aluminum plate is about 0.04 times of the excitation wavelength, and the position error is about 0.4 times of the excitation wavelength. The research work has made a beneficial exploration for the quantitative identification and evaluation of defects in structures. © 2021 Acta Acustica.

摘要 ：

针对传统全矩阵数据采集数据量大、采样时长随阵元个数增加的问题,提出了一种基于压缩感知的超声阵列全矩阵数据重构方法.根据多阵元等幅同步有限次激励下采集的超声信号与全矩阵数据的压缩采样关系,利用多阵元等幅同步有限次激励下采集到的少量超声信号进行超声阵列全矩阵数据重构,并将重构数据用于缺陷的全聚焦成像.基于提出的数据压缩采集模式,开展了块状试件中缺陷超声相控阵检测实验,并分析了稀疏变换基、激励阵元个数、激励次数等因素对检测结果的影响规律.实验结果表明,提出的方法可以在75％压缩率下实现超声全矩阵数据的重构,重构数据与实际全矩阵数据的均方根误差约为6％,可用于缺陷的全聚焦成像.

摘要 ：

For an operating wind turbine, the main shaft suffers severe structural damage. The surface breaking transverse crack threatens the safety of drive-train system directly. The crack examination method is available by diffracted waves in the central hole. In this research, an electromagnetic acoustic transducer (EMAT) for receiving diffracted longitudinal waves is proposed. Firstly, the converse piezomagnetic stress coefficients and magnetostriction coefficient were derived from the measured magnetic characteristic curve. The measured parameters were provided for sensor simulation. Considering the two coupling mechanisms, a receiving EMAT model was established for coil optimization. Secondly, the influence of materials, lift-off distance and cable type on sensor impedance would be analyzed in detail. Multiple factors were taken into account for impedance matching, and the signal amplitude was improved significantly. The angle divergence of the EMAT was also measured, showing the main lobe with 24 degrees. The crack detection experiments were carried out on a shaft sample. The results show that the developed EMAT can achieve the reception of diffracted longitudinal waves, and the signals are distinguishable. The crack was evaluated simultaneously by the received diffracted waves, and the errors showed less than 3 mm.

摘要 ：

In the case of assuming that the debonding interface layer was a thin fluid layer and taking the structural boundary conditions into consideration, we derived the expressions of ultrasonic reflection/transmission coefficients in a thick adhesive layer composite structure with debonding and slip defects under water immersion conditions based on the global matrix method. In addition,the finite element method was used to calculate the ultrasonic reflection/transmission coefficients when the bonding interface is debonded and slipped in the bonding structure. The theoretical calculation and simulation results are in complete agreement. The influences of the position of the interface defects (upper or lower interface of the adhesive layer) and defect types (slippage, debonding) on the ultrasonic reflection characteristics were also studied. The results show that if the incident angle and frequency of the sound wave are set appropriately, the perfected bonding, slippage and debonding interfaces can be distinguished.

摘要 ：

Based on the principle of ultrasonic testing, the non-contact ultrasonic time-domain simulation testing method was developed for the debonding and weak bonding defects of composite structures. Firstly, the time-domain simulation model of the ultrasonic transmission characteristics of single-layer CFRP (carbon fiber reinforced polymer) plate is established, and the frequency spectrum of the transmission coefficient is obtained. By comparing with the plane wave theory, the results show that the simulation results are in good agreement with the theoretical calculation. Then, the ultrasonic transmission coefficient of single / double interface weakening and cohesive weakening in composite bonding structure is simulated. The simulation results show that with the decrease of interface stiffness and the deepening of cohesion weakening, the local extreme points in the transmission coefficient spectrum tend to shift to the low frequency side, and the offset of the extreme points caused by the decrease of spring stiffness is different at different frequency points.

摘要 ：

Since the permeability of ferromagnetic materials is sensitive to the stress changes, it is feasible to acquire the stress level through detecting the change in permeability. In this study, to explore the distribution of stress or residual stress along the depth direction, a multi-layer model was established and a new inversion algorithm was proposed; and the hypothesis of uniformity of the material's physical properties for each layer was introduced. Under laboratory conditions, the four-point bending experiment was then implemented with a sample of 45# steel. Global Fourier series fitting based on the least-squares method was used for signal process. The amplitude ratio of the induced voltage to the excitation current was extracted. The effective permeability and the associated hysteresis angle at the 0.25 mm deflection were calculated and presented good regular variations. Finally, under the 0.25 mm deflection, the effective permeability change along the depth was obtained, and the inversely fitted curve was consistent with the theoretical curve. It is verified that the sensor has good robustness by adding deviation of the detection depth. Thereby, it is feasible to test stress or residual stress as a function of depth by multi-frequency eddy current (EC) method.
