Abstract
PURPOSE: To damp vibrations by forming a vibration-isolation device which is provided with a first permanent magnet arranged inside a hollow housing, a coil wound on a second permanent magnet sliding along a core extending through the center, and a current supply portion for the coil. CONSTITUTION: A column member 2 of a vibration-isolation device 3 is formed by hermetically coupling a non-magnetic housing 4 and both ends of a core 5 extending through the center in the housing 4. Further, a first permanent magnet 6 is arranged along the internal wall of the housing 4, and a slidable permanent magnet 7 is disposed along the peripheral surface of the arbor 5, followed by winding a coil 8 on the magnet 7. Then, a spring 9 formed of a conductive material is provided such that one end thereof is in contact with the magnet 7 and the other end thereof is in contact with an end wall of the housing 4. Further, the one end of the spring is electrically connected to the coil 8 and the other end of the same is connected to a power source via a current supply control arithmetic section. In this manner, driving current applied to the coil 8 having a dynamic mass is made into a special pulse, whereby a large braking force can be obtained with respect to ultra low frequency vibrations.
