A Very Low Temperature Vibration Isolation System
Very low temperature refrigerators are a significant source of low frequency vibrational and acoustic noise, which is a serious challenge to research using high sensitivity mechanical oscillators, or to high resolution scanning tunneling microscopes. We describe the design and operation of a vibration isolation system which is used at very low temperatures. The system consists of four masses su...
متن کاملVibration Isolation System Using Zero-power Magnetic Suspension
A new vibration isolation system is proposed which uses zero-power magnetic suspension. Since a zero-power system behaves as if it has a negative stiffness, combining it with a normal spring can generate infinite stiffness against disturbances on the isolation table. It enables the system to have good performance both in reducing vibration transmitted from ground and in suppressing direct vibra...

متن کاملVibration Isolation using a Shunted Electromagnetic Transducer
By attaching an electromagnetic transducer to a mechanical isolation system and shunting the terminals of the transducer with electrical impedance, we can provide improved isolation performance while eliminating the need for an additional sensor. Simulated and experimental results on a simple electro-mechanical isolation system show that the proposed controller is capable of peak damping and hi...
متن کاملStochastic resonance in a nonlinear mechanical vibration isolation system
This paper concerns the effect that a stochastic resonance can have on a vibration isolation system. Rather than reducing the transmitted force, it is shown that it is possible to significantly mask the component of the force transmitted though the isolator, when the system is excited harmonically. This can be achieved by adding a very low intensity of random noise to the harmonic excitation fo...
