Devices are clustered into their respective shock groups, but some devices maintain their superior performance even in the face of extreme shock. This work expands on the previous work of understanding shock resistance in gyroscopes and which devices may maintain performance under various conditions.","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121438833","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 this study, we propose a dynamically balanced out-of-plane resonator to increase the out-of-plane quality factor (Q-factor). A balanced dual-mass structure is designed to reduce the torque applied to the supporting substrate, and thus increase the Q-factor of the out-of-plane mode. Design optimization for frequency matching, reducing mechanical deformation and increasing Q-factor through finite element method (FEM) simulation has been demonstrated. Manufacturing method of the device employing Au-Au thermo-compression bonding has been developed. The fabricated resonator oscillated at around 4380 Hz after remove by using an externally stacked piezoelectric actuator and laser Doppler vibrometer (LDV).","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121931753","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 internal resonance can effectively improve resonators’ frequency stability, while the Stokes pump utilizes modal coupling to realize the amplification of the low-order mode’s sensitivity, making them become research hotspots recently. However, conventional phonon cavity manipulation studies focus on typical linear or nonlinear modes’ coupling. There are few reports on the Stokes pump experiment using a nonlinear mode where internal resonance occurs as the cavity mode. Compared with previously reported mode coupling experiments, this paper illustrates a novel coherent phonon manipulation method to combine advantages of the internal resonance and the Stokes pump. This paper reports the observation of coherent phonon manipulation in a disk gyroscope with internal resonance. We demonstrate that, by applying pump excitation on a resonator’s internal resonance mode which acts as a cavity mode, resulting in the occurrence of a self-sustaining oscillation on its low-order manipulated mode, it is possible to improve the gyroscope’s mechanical band width more than 2 times.","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130789423","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 this paper, the output model equation adopted for conventional gravimeters is revisited to describe the performance of novel MEMS gravimeters. We propose a model equation suitable for the MEMS gravimeter applied on the stationary base, and accordingly calibrate the MEMS gravimeter developed in our group by a discrete multipoint rotating test on a dividing head. A special configuration is empolyed, where the sensitive input axis of the gravimeter is perpendicular to the mounting surface. Subsequently, the requirements for levelling and horizontal acceleration noise of application environments are determined. The proposed model equation and mounting configuration are demonstrated suitable for calibrating MEMS gravimeters.","PeriodicalId":244190,"journal":{"name":"2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125059539","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}
