Background technology
The nuisance vibration of ship power plant is always a problem receiving much attention, and nuisance vibration not only can produce air Noise pollution, What is more can destroy structure.For military boats and ships, the vibration of its dynamic power machine then has more specifically endangers Evil, it can produce hull radiated noise, the disguise on impact naval vessel, increase simultaneously by the underawater ordnances such as sonic mine destroy can Can property.Therefore people have been working hard carry out improvement and the control of dynamic power machine vibration noise.
Traditional passive vibration isolation technology is effectively vibration control means, and its principle is on dynamic power machine and basis Between add elastic damping element, make the two produce impedance unbalance, thus reduce vibration to basic transmission.Common is several Vibration isolation way has single-layer partiting polarization, double-layer vibration isolating and buoyant raft vibration isolation, now begins to cabin raft truss structure.Passive vibration isolation system Itself there are the contradictory requirements that it cannot overcome.In order to improve vibration isolation efficiency, the spring of shock absorber will have sufficiently low rigidity, but It is to ensure that certain bearing capacity and stability, need larger static rigidity again；The damping of shock absorber can reduce altogether Vibratory response at vibration frequency, but energy transmission can be increased thus reducing vibration isolation efficiency in high band.It is important that The design of vibrating isolation system once completes, if outer scrambling rate changes, cannot ensure vibration isolating effect.These are passive vibration isolations The chronic illness of system, in order to solve problems, can adopt active Vibration Isolation.The principle of active Vibration Isolation is according to controlled The vibration information of system introduce active controlling force in systems so as to the vibratory response that produces with need vibratory response etc. of controlling Anti-phase, to reduce vibration to basic transmission.Therefore active Vibration Isolation can not only effectively damping low-frequency vibrations moreover it is possible to suitable Should outer scrambling rate change.
Because power ratio source of the gas and oil sources are simple, thus electrodynamic type and electricmagnetic actuator obtain in active control Extensively apply.The principle of electromagnetic actuator structure is to produce electromagnetic force (electromagnet principle), and what electrodynamic type executing agency utilized It is Lorentz force (principle of motor).Electricmagnetic actuator, can be in less execution body compared with electrodynamic type actuator Under long-pending and magnetic field, produce bigger power, but changed by air gap during work, easily cause non-linear.
