Innovative Solution of Torsional Vibration Reduction by Application of Pneumatic Tuner in Shipping Piston Devices

The industries of shipping, shipbuilding and port operations are among those in which mechanical drives with piston machines widely used. wide use is the result many years experience development modernization machines. Usually, they operate as constant operating speeds, exception combustion engines, a wider range speeds. limiting condition innovation machines, resulting from nature machine operation, torsional oscillation. effort to decrease an energy demand requires application non-traditional working modes, can be considered deactivation cylinders or expansion speed range. One possibilities eliminating these factors pneumatic tuner drives, which, contrast traditional solutions, has stiffness that smoothly changed. During experimental measurements resonance area, at 700 rpm after change, vibration value 15 Nm decreased 5 Nm.
