摘要: Summary The relative vibrations of two small frames with different stiffness, subjected to the same oscillating excitation coming from their base platform, were investigated. The effects innovative coupling standard passive attenuation and time variation magnetic forces (self-produced by vibration itself) first experimental tests demonstrate that amplitude can be easily decreased up 75% without requiring external energy. In perspective, varying attenuator shape power, it is possible use in all cases which necessary reduce a breakable or unstable structure inside building accidentally exposed vibration, such as rotor frame shelf museum room.
