Abstract
An apparatus for minimizing the transmission of vibrations from an un-sprung mass object to a sprung mass object through continuous control of system natural frequency and damping ratio including an air spring, a source of high pressure compressible gas, a vacuum source, a variable volume accumulator and a gas flow rate control valve to allow specified gas flow between the air spring and the accumulator thus generating variable system natural frequency and damping ratio.
