Abstract
This paper presents a vibration isolation system by using an active zero-power control incorporated with a passive technique. A positive stiffness spring is connected to a negative spring of equal magnitude in series to generate a high stiffness for on-board generated direct disturbances. The system is capable of isolating floor vibration as well due to the use of lower positive spring in the lower suspension. To reduce the load that the zero-power control system supports, a weight support mechanism is introduced. The proposed system paves the way for developing low cost vibration isolator with no power consumption in the steady-state. The mathematical model is analyzed such that it can generate infinite (high) stiffness for direct disturbance which is verified by experimental demonstrations.
