Three -dimensional dual -frenquency pipeline shock absorbing means

The utility model discloses a three -dimensional dual -frenquency pipeline shock absorbing means belongs to vibration noise control technical field. The device is including integrated seat, clamp andthree dual -frenquency bump leveller, the dual -frenquency bump leveller includes rectangle cantilever beam and two quality pieces, two quality pieces pass through the movably fixed connection of bolton the rectangle cantilever beam, three dual -frenquency bump leveller and integrated seat fixed connection, the top fixed connection of integrated seat and clamp, clamp and pipeline fixed connection, the axis of fixing the bolt of quality piece on the three dual -frenquency bump leveller corresponds the axial of pipeline, radial and vertical respectively. Two positions of quality piece on the rectangle cantilever beam of adjustment dual -frenquency bump leveller make its first -order modal's frequency correspond the axle frequently, and second -order modal shape's frequency corresponds the leaf frequently to the vibr
