METHOD OF DAMPING VERTICAL OSCILLATION OF OBJECTS WITH PNEUMATIC SUSPENSION Russian patent published in 2011 - IPC F16F15/23 F16F9/05 

FIELD: machine building.

SUBSTANCE: method consists in periodic decreasing restoring force of pneumatic suspension at beginning of each stroke of release by means of supplying additional volume of gas to one additional flexible element (4) from autonomous source of power (7) and by means of its withdrawal from this additional flexible element (4) at beginning of each stroke of compression to atmosphere. Additionally, at the beginning of each stroke of compression there is performed periodic supply of additional volume of gas to the second additional flexible element (5) from autonomous source of power (7), while its withdrawal to atmosphere from second additional flexible element (5) is made at the beginning of each stroke of release.

EFFECT: control of flexible damping characteristics of pneumatic suspension in all amplitude-frequency range of external force.
