Active Vibration Attenuation Using Four-rotor Mechanical Actuator

Active vibration attenuation using mechanical actuator is a new technique in ship vibration control field. First this paper introduces the basic principle of a new four-rotor mechanical actuator. Then originated from the theory of active vibration attenuation and based on practical needs for mechanical actuator, a kind of analytic algorithm called phase adjusting analytic algorithm is proposed to calculate its optimal phase and eccentric distance. As it works with mechanical actuator, the active vibration attenuation effect will be better.
