In this paper, three intelligent algorithms with global search capabilities, the ant colony algorithm (ACA), the genetic algorithm (GA) and the simulated annealing algorithm (SAA), are introduced into DVC. Through simulated speckle experiments, the search accuracy and speed of these three algorithms are studied and compared. The results of simulated speckle experiments show that: (1) The accuracy of the ant colony algorithm is the highest, followed by the genetic algorithm, and finally the simulated annealing algorithm, with average relative errors of 0, 3.6% and 3.9%, respectively. (2) The genetic algorithm is the fastest, followed by the simulated annealing algorithm, and finally the ant colony algorithm. The time-consuming of the three algorithms is 10%, 11% and 23% of the enumeration method.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"34 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":"130239089","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}

To investigate the impact of holes in composite plate, some holes are added to the plate. The finite element method is used to calculate the dispersion curves. The impacts of geometric and material factors on the band gap are contrasted and investigated. The results reveal that a low-frequency band gap may be achieved by using the proper geometric parameters and materials, and more broader band gap can be obtained by altering the density of cement-based piezoelectric composite material. The band gap can also be affected by the magnitude of the holes.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"3 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":"115997324","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}

Functionally graded piezoelectric material (FGPM) is an extraordinary functional graded material coupled with elastic and electric fields. To calculate the mechanical response of the piezoelectric gradient structure under quadratic distribution of thermal gradient accurately, a thermo-electro-elastic coupled simulation for piezoelectric gradient structure under nonlinear thermal field is proposed based on the FOSD hypothesis. The influences of material distribution, thickness and aspect ratio on the deformation of the structure under the nonlinear thermal gradients are obtained by parameteric investigation. The mechanical response results demonstrate that the numerical computation accuracy improves efficiently by considering the thermal distribution effect on FGPM.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"14 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":"133234687","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}

Meanwhile, the complexity of corrugated structures will take up massive computing time and waste computing resources in the simulation. Here a sandwich laminated structure is proposed with enhanced damping characteristics through the filling of viscoelastic material into the corrugated layer. With the consideration of periodic boundary conditions (PBCs), three dimensions (3D) homogenized method is adopted to link the representative volume element (RVE) to the global structure.

The finite element software was used to simulate the surface waves and longitudinal waves generated by the piezoelectric materials due to piezoelectric effect and the laser through thermal expansion, and the probe point was set to receive ultrasonic signals. The elastic constants of materials can be determined from the relationship of the longitudinal wave and surface wave sound velocities with the Poisson’s ratio and elastic modulus. The simulation results are in good agreement with the theoretical values, indicating that the established finite element model can effectively simulate the physical process of ultrasonic wave generation.

A force sensor with four strain gauges is integrated with the flexure mechanism to measure the pinching force.

The spectral intensity value is calculated according to the range of lgSI0.2 calculated. Finally, the ordinary Kriging interpolation method is used to draw the spectral intensity contour map. The improved method proposed in this paper establishes a continuous function relationship between the acceleration time-history integral of ground motion and the spectral intensity. Through the comparison and verification of two earthquakes, the spectral intensity contour map obtained by the improved algorithm is consistent with the overall change trend of the macroscopic intensity map, and has a good corresponding relationship.
