Abstract

A new hybrid vibration isolator (HVI) with an laminated piezoelectric actuator used as an active vibration isolation component and viscoelastic material used to design a passive vibration isolation component was proposed to reduce the effects of vibration loads on structures. Taking a simulated rigid satellite as a study object, the dynamic model of the wholespacecraft hybrid vibration isolation system was established to analyze the vibration isolation principle of a HVI numerically. Then, the singleinput multipleoutput PID control method was used to design an active controller, tests were performed for the simulated rigid satellite hybrid vibration isolation system. The simulation and test results showed that a HVI can effectively reduce the vibration loads transmitted to structures compared with a pure passive vibration isolator, especially, near natural frequencies of structures, so the safety and reliability of structures can be improved significantly.
