Itself there is its contradictory requirements that can not be overcome.In order to improve vibration isolation efficiency, the spring of shock absorber will have sufficiently low rigidity, but
It is to ensure certain bearing capacity and stability, needs larger static rigidity again；The damping of shock absorber can reduce altogether
Vibratory response at vibration frequency, but can increase energy transmission in high band so as to reduce vibration isolation efficiency.It is important that
The design of vibrating isolation system, if outer scrambling rate changes, can not ensure vibration isolating effect once completing.These are passive vibration isolations
The chronic illness of system, in order to solve problems, active Vibration Isolation can be used.The principle of active Vibration Isolation is according to controlled
The vibration information of system introduces active controlling force in systems, makes the vibratory response etc. that its caused vibratory response and needs control
It is anti-phase, to reduce transmission of the vibration to basis.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 and easy, thus electrodynamic type and electricmagnetic actuator obtain in active control
Extensive use.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 product and magnetic field, air gap change, easily causes non-linear when producing bigger power, but being worked.
