COMPENSATION PENDULOUS ACCELEROMETER

摘要

measurement of acceleration. SUBSTANCE: proposed accelerometer has case housing pendulous unit made of one plate of silicon monocrystal and carrying mobile blade arranged on elastic suspension and bearing frame with protrusions. Two electric insulation aids are anchored on both sides of bearing frame on protrusions. Two magnetic systems are fixed on proper electric insulation aid. Two coils of torque generator with leads are arranged in gap of corresponding magnetic circuit and are attached to proper side of mobile blade. Elastic suspension includes at least two elastic elements placed at angle of 90 degrees one relative another in symmetry with respect to symmetry axis of pendulous unit. Electric insulation aid is manufactured in the form of bushing that embraces magnetic circuit of magnetic system over external side surface and bearing frame of pendulous unit rests against butts of bushings forming common planes with end faces of magnetic circuit facing pendulous unit. EFFECT: increased accuracy of measurement of acceleration vector with keeping or reduction of dimensions, enhanced vibration stability. 10 cl, 10 dwg
