FIELD: mechanical engineering; vibration isolation of processing equipment.
SUBSTANCE: at vibration isolation of variable-mass objects, such as looms, by means of elastic element, damping is effected over entire range of amplitude-frequency characteristic by separating friction surfaces of friction bushing into inner and outer surfaces with possibility of regulation of friction coefficient by of adjusting screws coupled with slave servomotor, for instance, worm type servomotor with self-braking transmission. Signal to switch of servomotor is sent by microprocessor which controls operation of dry-friction damper according to preset characteristics and is coupled with vibration acceleration transducer, for instance, piezocrystal one.
EFFECT: improved efficiency of vibration isolation.
