However, due to the complicated damage mechanism of lightning strikes, the lightning strike damages are usually detected with traditional NDT technologies, which is inapplicable for online monitoring. In this paper, a piezoelectric-guided wave imaging method to monitor lightning strike damages of composite structures is present. The damage mechanism of lightning strikes on composite structures is firstly investigated. Then, the piezoelectric-guided wave imaging method of lightning strike damages is developed. Finally, an ABAQUS simulation on a carbon fiber reinforced plastic (CFRP) composite plate is conducted to validate the effectiveness of the proposed piezoelectric-guided wave imaging method.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"166 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":"123004414","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 QZS property is realized by combining the inclined beams with negative stiffness and the circular arches with positive stiffness. Mechanical model of the mechanism is derived theoretically, and a parameter design based on Taguchi method is carried out, leading to the mechanism with ultra-low stiffness. After that, static characteristic of the mechanism is simulated and is approximately consistent with the theoretical results. On this basis, the dynamic behavior of vibration control is analyzed to study the vibration isolation performance. Simulation results show that the proposed mechanism can provide constant preload force (about 5.2 N) and have better vibration isolation performance at low frequency.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"52 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":"116610948","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 research shows that compared with the one-end hinged support, the new clamping structure reduces the normal stiffness and tangential stiffness of one-end hinged support, and the clamping structure is symmetrical, with better modal consistency and the same running speed in both directions. Due to the flexible hinge structure, the speed fluctuation of the motor is small when running.

Recently, the numerous research findings of locally resonant metamaterials have been achieved to improve the absorption functionality in the low frequency vibration. The dispersion curves of ABSPMMA polymer bipanel have been studied by using the finite element method (FEM) and their flexural wave bandgap with the steel mass blocks has been computed in ultralow frequency range from 54 Hz to 65 Hz at the subwavelength size. The frequency domain with negative density is the good agreement with the flexural wave bandgap. Thus, this original metamaterial bipanel with the resonance blocks can render the flexural wave bandgap to control the ultralow frequency vibration.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"2 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":"123936940","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}
