It is necessary to propose an accelerometer configuration measurement model that yields such a high measuring precision. In this paper, an accelerometer configuration to improve measurement accuracy is proposed. The corresponding calculation formulas of the angular acceleration were derived through theoretical analysis. A method is presented to minimize angular acceleration noise based on analysis of the root mean square noise of the angular acceleration. Moreover, the influence of installation position errors and accelerometer orientation errors on the calculation precision of the angular acceleration is studied. Comparisons of the output differences between the proposed configuration and the previous planar triangle configuration under the same installation errors are conducted by simulation. The simulation results show that installation errors have a relatively small impact on the calculation accuracy of the proposed configuration. To further verify the high calculation precision of the proposed configuration, experiments are carried out for both the proposed configuration and the planar triangle configuration. On the basis of the results of simulations and experiments, it can be concluded that the proposed configuration has higher angular acceleration calculation precision and can be applied to different platforms.<\/jats:p>","DOI":"10.3390\/s150820053","type":"journal-article","created":{"date-parts":[[2015,8,18]],"date-time":"2015-08-18T02:36:16Z","timestamp":1439865376000},"page":"20053-20068","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Measurement Model and Precision Analysis of Accelerometers for Maglev Vibration Isolation Platforms"],"prefix":"10.3390","volume":"15","author":[{"given":"Qianqian","family":"Wu","sequence":"first","affiliation":[{"name":"School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150001, China"}]},{"given":"Honghao","family":"Yue","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150001, China"}]},{"given":"Rongqiang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150001, China"}]},{"given":"Xiaoyou","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Nippon Institute of Technology, Saitama 345-8501, Japan"}]},{"given":"Liang","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150001, China"}]},{"given":"Tian","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Engine and Energy, Northwestern Polytechnical University, Xi\u2019an 71000, China"}]},{"given":"Zongquan","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150001, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"469","DOI":"10.2514\/3.20134","article-title":"Future payload isolation and pointing system technology","volume":"9","author":"Laskin","year":"1986","journal-title":"J.
