VIBRATION-PROOF SUPPORTING DEVICE FOR MOUNTING ELECTRONIC COMPONENTS Russian patent published in 2002 - IPC

FIELD: machine engineering, possibly protection of components of radioelectronic equipment against vibration loads. SUBSTANCE: supporting device includes elastic mounting plate and elastic rectangular frame arranged mutually in parallel. Frame is rigidly secured to plate along its periphery and it is elastically joined with plate in central portion with possibility of mutual motion of frame and plate. Elastic joint of central portions of frame and plate is in the form of flexible twisted belt whose outer ends are secured to frame and plate. Belt has two portions twisted in mutually opposite directions and divided by rigid partition. The last is in the form of cover strip secured to belt and engaging by its plane turned to frame with inner surface of frame from its central portion until periphery. EFFECT: enhanced efficiency of vibration insulation due to automatic breaking of resonance modes. 2 dwg
