TUNED MASS DAMPER OF SHIP ENGINE FOR VIBRATION DIMINISHING

摘要

PURPOSE: A tuned mass damper of ship engine for vibration diminishing is provided to diminish a vibration of an engine by moving a damper having a same natural frequency with a rated number of rotations of the engine to an opposed direction to the direction of vibration of the engine, always. CONSTITUTION: A tuned mass damper of ship engine for vibration diminishing diminishes a vibration of an engine by moving a tuned mass to an opposed direction to the direction of the vibration of the engine. An adjustment of a natural frequency in the tuned mass damper is implemented by altering a rigidity of a spring for supporting the tuned mass, or by adjusting the largeness of the tuned mass by adding/subtracting additional mass. Further, oil pipes are installed on the tuned mass damper to cool a heat occurred from the spring moving always corresponding to the vibration of the engine and make a viscosity damping effect by a constant oil.
