Abstract
In order to effectively control the broadband and low-frequency line-spectrum vibration transmission of ship power machinery, a passive-active hybrid vibration isolation mount using electromagnetic actuator and air spring was designed. From the theoretical analysis of electromechanical coupling characteristic of electromagnetic actuator and the dynamic characteristic of hybrid vibration isolation system, a parameter design method which meets the needs of line-spectrum vibration control and hybrid isolation performance was proposed. An improved multi-channel FxLMS algorithm was proposed, which could reduce the calculation complexity when the damping of the system is small and efficiently compensate the nonlinearities of the actuators at the same time. Experiment results show that the theoretical analysis is correct, and the technology has superiority of low power consumption, good stability and excellent broadband and low frequency line-spectrum vibration control effect.
