SYSTEM OF ACTIVE VIBRATION PROTECTION AND STABILISATION Russian patent published in 2010 - IPC B60G17/15 B60G17/48 F16F9/504 

FIELD: transport.

SUBSTANCE: invention relates to machine building and can be used to control vibrations of damped mass and to stabilise its static position. Said system comprises suspension that incorporates hydraulic engine with double-acting electro hydraulic booster. Hydraulic engine plunger is articulated via flexible element with stabilised mass. Hydraulic engine power cylinder casing is coupled via flexible element with wheel axle or vehicle frame. Said system incorporates controller to generate control law on the basis of preset reference properties of motion and current state of stabilised mass and hydraulic engine plunger. One of controller inputs is connected via acceleration transducer with stabilised mass, while another input is connected via power cylinder casing current collector and double-way rod bars with feedback potentiometre. The latter controls power cylinder plunger positions at every time interval. Controller output is connected with electro hydraulic booster input.

EFFECT: reduced accelerations, higher accuracy of stabilisation.
