Abstract
The present invention relates to a method for vibration isolation featuring a two-part supporter made up of two supporters with positive and negative spring characteristics that are connected in series, and another supporter with positive spring characteristics that is installed in parallel with the two-part supporter. Vibration from the floor to the first member is isolated by the springs installed between the floor 1 and the first member 2; vibration transmitted from the first to the second member is isolated by the magnetic levitation mechanism 4 with zero-power characteristics comprising permanent magnets and electromagnets that are installed between the first member 2 and the second member 3 and by the load supporter 5 with positive spring characteristics that is installed between the base and the second member; and the load acting on the second member is supported by said magnetic levitation mechanism and said load supporter.
