SHOCK ABSORBER Russian patent published in 2002 - IPC

FIELD: mechanical engineering; vibration protection technique; transport engineering for protection of operator against wide-band random kinematic disturbance. SUBSTANCE: shock absorber includes two bases, load-bearing flexible member secured between both bases, additional flexible member, control unit, two speed sensors mounted on these bases and connected to respective inputs of control unit. EFFECT: possibility of realizing optimal controllable process of change-over of stiffness: additional flexible member is placed in operation only when its restoring force reduced absolute velocity of first base. 1 dwg
