摘要
A single-degree-of-freedom magnetic vibration isolation device belongs to vibration isolation devices and solves the following problems: the existing active and passive combined vibration reduction system is complex in structure, needs energy supply, and has low reliability. The present invention includes a metal conductor sleeve, a base, an upper annular permanent magnet, a lower annular permanent magnet, a connecting rod and a center permanent magnet; poles of the upper annular permanent magnet and the lower annular permanent magnet facing to each other have reverse polarity, which are connected to an upper end and a lower end of an inner wall of the metal conductor sleeve respectively; the center permanent magnet is concentrically sleeved on the connecting rod and fixedly connected therewith, and the center permanent magnet is located between the upper annular permanent magnet and the lower annular permanent magnet, and is capable of moving axially together with the connecting rod between the upper annular permanent magnet and the lower annular permanent magnet; and the pole of the center permanent magnet facing to the poles of the upper annular permanent magnet and the lower annular permanent magnet have reverse polarity. The present invention is simple in structure, does not need energy supply, has high reliability, and can generate a static magnetic force and a dynamic magnetic force. Connecting the device according to the present invention with a passive vibration isolation system in parallel can effectively improve the passive vibration isolation performance of the original system.
