【Abstract】 A new type of adjusting eccentricity mechanics is studied in the paper. The problem of line moving of the eccentric mass along the shaft with rotation of the shaft is solved. The principle of the actuator is that two eccentric gyrating mass moving in opposite direction to produce a single direction exciting force by mechanics to counteract the upright vibration of the ship caused by the imbalance moment of the engine. The magnitude of vibration caused by engine and actuator is the same and in opposite direction that its phase angle is 180 degree and the vibration is counteracted.更多还原
