The acoustic-structure coupling method was adopted to carry out the underwater explosion simulation research of the cabin under four cases, where the shock factors of the plate-shell were 0.57, 0.65, 0.83 and 1.11 respectively, mainly collecting the impact vertical acceleration. The influence law of different underwater explosion impact intensity on the shock environment of typical equipment in cabin was analyzed. The results show that the greater the shock factor, the greater the peak stress that the cabin will withstand, and the growth rate will gradually tend to be flat; the spectral velocity amplitudes of the same part are not significantly different; the maximum spectral velocity obtained by the measurement appears at the deck equipment, and there is a gradual attenuation trend as the position moves down.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"20 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":"116541559","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}

Due to the special structure in the pump body, the uncovered area phenomenon is occurred when the pump is working and it effects the output performances. In order to analyze the flowing states and output performances of the valveless piezoelectric pump under the uncovered area phenomenon, the article proposes a valveless piezoelectric pump with inverted petal combination structures. The structures and working principles are described. Then we analyze the output flow rate in theoretically. Finally, we use the ANSYS CFX to simulate the flow state inside the chamber under the different parameters of the opening interval with 0mm, 0.5mm, 1.0mm, 1.5mm and 2.0mm and resistant structure radius at 2.5mm, 4.0mm, 5.5mm, 7.0mm, 8.5mm and 10.0mm. The result shows that when the opening interval is 1.0mm and the resistant structure radius is 5.5mm, the simulation flow rate achieves the maximum of 198.59mL/min, the positive loss pressure is 48.192Pa and the reverse loss pressure is 53.66Pa. Using the uncovered area phenomenon improves the pump performances effectively, the article provides the reference value for valveless piezoelectric pumps.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"29 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":"123830590","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}

These large structures suffer from dynamic loads, such as structural deformation and low-frequency vibration caused by on-board equipment and the thermal shock. In this paper, twisted and coiled polymer actuators (TCPAs) were used to suppress the low-frequency vibration of flexible structure. Two TCPAs were symmetrically mounted on both sides of a cantilever beam, to generate sinusoidal actuation force. The model of thermally driven TCPA was developed for force control of TCPAs, and a dynamic response model of cantilever beam with TCPAs was then proposed. Actuating experiment in forced air was implemented based on proposed model using identified parameters from experimental data. The results showed that in actuating experiment, the average errors between the experiment and model are within 5% at different current amplitudes.","PeriodicalId":387693,"journal":{"name":"2022 16th Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)","volume":"7 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":"130312141","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}
