Active vibration control apparatus with adjustable excitation force mechanism

摘要

An apparatus for attenuating vibration in an object equipped with a vibrating source, comprising: a vibration compensator (20) for varying the angle of the weight (22) corresponding to the vibration of the vibrating source; An active vibrator (30) which varies the weight of the weight corresponding to the load state of the target object; And control means (40) for varying the amount of fluid (36) flowing into the cavity (31) of the active vibrator (30). Accordingly, since the structure for adjusting the rotational unbalance mass and the excitation force based on the flow of the fluid is adopted, it is easy to adjust the excitation force corresponding to the load condition of the ship, thereby enhancing the effectiveness of vibration reduction maintenance for the residence.
