The mode expansion method is used to calculate the transient response when the excitation is applied on the surface. Numerical examples and FEM simulations are given and they are in good agreement. Based on previous procedure, the time-domain Green’s functions are obtained. After that, an inverse scattering method is proposed by use of boundary integral equation about the scattered wave field in time domain. With introduction of Born approximation, an inverse scattering scheme can be formulated to reconstruct the locations and shapes of cracks and inner cavities. Results show that as long as time domain data are enough, a receiver array can obtain locations and rough images of cavities within the structure.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128924065","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}

In order to prevent the deterioration of the vibration control effect of the MFC actuator on the structure, it is necessary to propose an effective method to predict the function degradation of MFC. In this study support vector machine (SVM) is adopted in the function degradation prediction modeling of MFC. Aiming at the typical problem of stress-induced function degradation of MFC, a nonlinear prediction model based on SVM is established. The experimental data is used as samples to train the SVM model, and an effective method based on the established model for the function degradation prediction of MFC is proposed. The fitting error of the model to the experimental data is less than 1%, and the maximum prediction error for the MFC function degradation curve under 30MPa stress is 6.2%.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125371712","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}

In order to introduce the effect of micro-vibration, the dynamic model of the driving mechanism is directly considered in the micro-vibration control system. First, according to the working principle of the stepper motor and the reducer, the theoretical model and the equivalent dynamic model of the stepper motor and the harmonic reducer were derived; then, based on the Lagrange equation modeling method, the entire control system was derived as a nonlinear rigid-flexible and electromechanical coupling dynamics model, which includes the piezoelectric flexible arm, the stepper motor and the harmonic reducer. Furthermore, combined with the proportional velocity negative feedback control algorithm, a micro-vibration closed-loop control model was built using the Simulink platform, and the micro-vibration control effect was simulated and analyzed. The simulation results show that the single drive motor has a significant nonlinear effect on the micro-vibration response of the flexible arm. And the piezoelectric structure has a very effective micro-vibration control effect on the flexible arm driven by a single motor.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127796875","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 simulation results show that the improved gravitational search algorithm improves the phenomenon that the gravitational search algorithm is prone to prematureness and improves the global search capability and convergence performance of the algorithm.

The actuator adopts a fully open structure, which does not need to consider the problems of sealing and pressure resistance caused by deep-sea pressure.

By using piezoelectric ceramics, the second-order in-plane bending vibration of the stator is excited to drive the rotor to move back and forth along the inner diameter of the stator. A prototype is manufactured and a series of experiments are carried out to reveal its working performance, including the load characteristics of annular piezoelectric actuator, the relationship between swing frequency and driving frequency, and the relationship between swing frequency and voltage. The maximum load of the actuator is 0.2N, the optimal driving frequency is 1235Hz, and the swing frequency is directly proportional to the voltage.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128145184","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}

As one of the most mainstream non-destructive testing methods, ultrasonic testing relies on the knowledge of wave characteristics, i.e. dispersive properties and wave structures. In this paper, an eigen-frequency method is proposed to efficiently and accurately analyze the wave characteristics in metal-CFRP multilayer pipes, with the aid of Floquet periodic boundary conditions. Experimentally, a non-contact laser ultrasonic system is established to measure the multi-modal dispersion curves in a broad frequency range.

The hysteresis exhibits varying dynamics under the input signals of the different frequencies and amplitudes. To this end, the experimental characterization is conducted and hysteresis modeling approach is studied with the data-driven technique. Two characteristic indexes, i.e., loop relative width and loop asymmetry coefficients, are quantitatively analyzed. Based on the hysteresis phenomenon analyses, different modular models are selected and combined to describe those phenomena. The arctangent-polynomial modified Prandtl-Ishlinskii (APMPI) and infinite impulse response (IIR) submodels are applied for asymmetry rate-independent and rate-dependent hysteresis identification respectively. Those submodels are selected to construct a cascaded overall model to describe the hysteresis of magnetostrictive actuator.
