VIBRATION PROTECTION SYSTEM WITH THE CONTROL MECHANISM FOR ITS ELASTIC AND DISSIPATIVE PROPERTIES Russian patent published in 2018 - IPC F16F15/04 F16F3/04 F16F7/04 

Abstract RU 2645453 C1

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering. System of lower and upper lever arms in the form of a diamond is installed between the object of protection and the exciter of oscillations. Main spring and the base damper are installed along the small diagonal of the diamond. Additional dampers are mounted on both sides in parallel to the main spring and the base damper, which are connected by means of the sliding connections and adjusted by means of the control unit. Main spring is performed in the form of the dry friction spring damper. Damper consists of lower and upper support plates. Between the plates coaxially and concentric the external with right and internal with left angles of turns rise springs are installed. Lower support plate is base, on which springs lower flanges are rigidly attached. Between the top support plate and top flange of the internal spring the dry friction damper is installed. Damper consists of two contacting cylindrical discs. Bottom disc is rigidly linked with top flange of the internal spring. Top disc is rigidly linked with the top support disk. On facing each other surfaces of discs the concentric diametric grooves and inserted in them shoulders are made. As discs material copper-based sintered friction material can be used.

EFFECT: increased efficiency of vibration isolation is achieved by means of increasing the dissipative properties of the vibration protection system.
