METHOD OF VIBRATION INSULATION AT NON-LINEAR DAMPENING

摘要

FIELD: mechanical engineering; protection of technological equipment against vibrations.;SUBSTANCE: proposed method makes it possible to perform vibration insulation by means of spring-type resilient members in vibration insulation systems of objects at varying dynamic loads, for example looms. Method may be also used for performing unsymmetrical dampening when difference resistance is formed for compression stroke and release stroke by of dry friction damper at varying friction coefficient at compression and release strokes in vibration insulation system. Magnitude of varying friction coefficient is set by means of unsymmetrical friction surfaces. Varying magnitude of dry friction coefficient is also set by means of cam pair engageable with object to be vibration insulated through rack gear.;EFFECT: enhanced efficiency of vibration insulation due to creation of unsymmetrical characteristic of non-elastic resistance of dry friction damper.;3 cl, 7 dwg
