Vibration isolation system

(57) All the summary direction 防振 suspension systems (10) support in elasticity the object with which insulated equipment should be insulated to a payload platform (14) including some compound insulation equipment (12). Each compound insulation equipment (12) contains in horizontal movement insulation equipment the perpendicular movement insulation equipment by which operation connection was carried out. As for perpendicular movement insulation equipment, this spring is connected with a central hub assembly object (20) and a base platform (22) including a support spring (18). A spring (18) supports the payload weight transmitted to a central hub assembly object through the class leveling movement insulation equipment by which operation connection is carried out between the central hub assembly object (18) and the payload platform (14). The negative rigid mechanism is also connected with the central hub assembly object (20), and it reverse-acts to the positive rigidity of a spring (18). Operation connection of these is carried out at perpendicular movement insulation equipment including three 可撓 beam supports (36) by which class leveling movement insulation equipment was used as the cylinder rod.
