Theory on Measuring Orientation with MEMS Accelerometers in a Centrifuge

摘要: © ASCE 2015. Microelectromechanical systems (MEMS) sensors have become a common part of everyday life and can be found in number consumer electronics. Specifically, MEMS accelerometers widespread because their low cost, due to mass production techniques, ability sense constant acceleration. This allows devices, such as cellular phones, measure rotation relative Earth's gravity. These properties also make an option for measuring the geo-structures, foundations, field or scale model geotechnical centrifuge tests. appear especially beneficial orientation experiments they are not limited by design constraints traditional tilt sensors: single acceleration vector (Earth's gravity). paper presents theory behind using single-Axis object on plane reactive centrifugal gravity within centrifuge. The specifically addresses cross-Axis sensitivity which significantly impact measurements is typically excluded from simpler theories.
