DEVICE FOR IMPACT AND VIBRATION LOADS DAMPING Russian patent published in 2019 - IPC F16F15/27 

FIELD: machine building.

SUBSTANCE: invention relates to engineering. Device for shock and vibration loads damping contains intermediate mass installed on the first high-pressure sleeves. Sleeves are mounted on concrete box base, filled with working fluid and coupled pipeline with first check valve and first adjustable throttle connected in parallel. Valve and throttle are connected to the first hydraulic and pneumatic accumulator. Second and third high-pressure sleeves filled with working fluid are arranged between box walls and intermediate mass. Additional hoses are connected by pipelines through appropriate check valves and controlled throttles with hydraulic and pneumatic accumulators. Damping elements are arranged between all high-pressure hoses. All check valves and all adjustable throttles are connected to all valves accordingly. Valves are connected to pressure sensor, safety valve and filter. Filter is connected to the pump. Pump is connected with tank filled with working fluid. Hydropneumatic accumulators are connected to corresponding valves. Valves are connected to the check valve, the second safety valve and the second pressure sensor. Control system is connected to all elements and an accelerometer mounted on the intermediate mass.

EFFECT: higher efficiency of suppression of direct and non-direct impact and vibration effects.
