SENSOR FOR VINKELHASTIGHET OCH SPECIFIK KRAFT RELATIVT TVA AXLAR UNDER ANVENDNING AV VIBRERANDE ACCELEROMETRAR

摘要

An apparatus for inertially determining the rate of angular rotation and translational motion of a structure is provided which utilizes a pair of vibrating accelerometers vibrating along a single axis with their force sensing axis located normal to the axis of vibration and rotated 90 DEG from each other. Signals from the vibrating accelerometers can be processed to provide indications of angular rotation about two axes and translation motion about two axes. Two of the sets of vibrating accelerometers can be combined to provide a three axis inertial reference system.
