The developed theory is general. It is based on the kinematic model of the third approximation (Sheremetev-Pelekh-Reddy). Two other theories follow from it as a special case: the theory of nonlinear dynamics and flexible nano-plates, obtained on the basis of the kinematic model of the first approximation (Kirchhoff), the second approximation (Timoshenko). The general theory obtained follows from the variational principle of Hamilton. For each of the kinematic hypotheses, a system of nonlinear partial differential equations is obtained. Obtaining a “true” solution is guaranteed using the methodology outlined in [1]. As an example, the model of the first approximation of the nonlinear dynamics of flexible elastic axisymmetric nano-plates is studied. In a numerical experiment, the required equations are solved by different methods, their convergence is investigated. It is shown that taking into account the size-dependent parameter significantly affects the character of plate oscillation and changes their character.","PeriodicalId":243907,"journal":{"name":"2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115169260","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}

With the aid of the case rotation-dwell technology, the case-fixed drift of the ESG is largely averaged out and then the precision is mainly determined by the rotor roundness, electrodes geometry, suspension control law and circumstances stability. With the certain manufacturing limit and careful suspension system design, the factors of rotor roundness, circumstances stability and suspension fluctuation are already bounded to a certain level, so it is important to check the electrodes geometry to improve the performance of the ESG. In this paper, aiming to minimize the drift of gyroscope, the problem of determining the electrodes geometry is addressed with compromising suspension stiffness and practical realization. Firstly, a general drift model is put forward for arbitrary electrodes geometry and rotor attitude. It is found that the drift along the electrode axis vanishes when the rotor rotation axis coincides with this very electrode axis and the drift model turns to be simpler. Then, the effect of electrode shape on disturbing torque is analyzed with identical electrodes and isotropic stiffness. It is found that when the electrode shape is symmetrical about its geometry axis, the drift caused by cross-axis effect will be minimized and a simplest drift model can be potentially obtained with some sacrifices on suspension stiffness. Finally, two commonly used electrodes shape, hexahedral projection electrodes and spherical crown electrodes which respectively represents the potential maximal stiffness and the simplest form are compared with its drift magnitude, model cleanliness, suspension stiffness, disturbing torque, cross-axis effect and engineering realization. The result is useful in problem of electrode geometry selection.","PeriodicalId":243907,"journal":{"name":"2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124378318","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}

According to the navigation error propagation equations, the state equation and the measurement equation are constructed for the Kalman filter. The systematic calibration for MIMU reduces the reliance on the turntable and it doesn't need accurate rotation, which save much time. The static navigation test is carried out to test the effectiveness of the proposed algorithm, and the results show that the proposed calibration scheme can be easily implemented to estimate the errors of the accelerometers and gyros, including scale factors, axis misalignments, and biases. After compensation, the quality of IMU raw data is significantly improved.","PeriodicalId":243907,"journal":{"name":"2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116538098","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}
