TEST BENCH FOR MEASUREMENT OF VIBRATORY REACTION MOMENTS IN GYROMOTOR

摘要

FIELD: instrumentation.;SUBSTANCE: invention relates to instrumentation equipment, namely to instruments for the measurement of vibratory reaction moments of gyromotors. A test bench comprises a suspender, a chamber providing for the fixation of a gyromotor with its transverse or polar axes along the suspender axis, vibration measuring instrument in the form of the first magnetoelectric sensor with its windings being fixed in the device casing in the field of magnets set at the suspender axis and joined through a measuring amplifier with a signal measuring instrument and a power amplifier, the load to the latter is applied by the windings of the second magnetoelectric sensor set coaxially to the first sensor, the suspender is made as a shaft connected to the chamber and vertically installed in the bearings of the casing mounted on a base, current leads of the gyromotor are made as three springs with their opposite ends being joined with the chamber and the test bench body through contact plates.;EFFECT: improved accuracy and processability of control of gyromotor's vibratory reaction moments at the gyromotor production stage.;4 dwg
