    • PURPOSE: To effectively absorb vibration from the outside by constituting a magnetic spring out of at least two permanent magnets, and properly selecting the locus of movement of one of these permanent magnets relative to the other to specify the spring constant. CONSTITUTION: On the upper faces of the inclined bases 12, 14 of a fixed frame 6, for example, bipolar magnets 22, 24 are respectively fixed. A movable frame 8 is provided with bipolar magnets 38, 40 fixed to the inclined parts 36a, 36b formed on both faces of a bracket 36. In this case, the bipolar magnets 22, 24 and the bipolar magnets 38, 40 are arranged in parallel with each other in the condition of opposing the same magnetic poles to each other. In this constitution, according to a load mass fitted to a top plate 34, when the size and the inclination of the respective bipolar magnets are properly selected to set spring constant around an equibrium point to be nearly zero, even if vibration is input to either of the movable frame 8 or the fixed frame 5, the other can hardly receive influence of the input vibration.
    • 目的:通过从至少两个永磁体构成磁性弹簧,并从这些永久磁铁中的一个相对于另一个永磁体的移动轨迹来确定弹簧常数,从而有效吸收外部振动。 构成:在固定框架6的倾斜基座12,14的上表面上,例如双极型磁铁22,24分别固定。 可移动框架8设置有固定到形成在支架36的两个表面上的倾斜部分36a,36b的双极性磁体38,40。在这种情况下,双极磁铁22,24和双极磁体38,40平行布置 彼此处于彼此相对的相同磁极的状态。 在该结构中,根据装配到顶板34的负载质量,当适当地选择各个双极磁体的尺寸和倾斜度以将平衡点周围的弹簧常数设置为接近零时,即使振动被输入到任一个 可移动框架8或固定框架5,另一方难以接受输入振动的影响。
