PURPOSE:To manufacture a large-capacity oscillation table of simple structure at low coast by providing a platen for an object and isolator arranged under the mount part constituted by stacking plural metallic plates and >=1 elastic plate alternately. CONSTITUTION:The oscillation table A has the plane frame type platen 4 where a reduced model of a building is mounted and the isolators 1, 1- for supporting the platen 4. The isolators 1, 1- are fixed at four corners of upper fitting plates 1a and 1a. Those isolators 1, 1- have a large spring ratio (vertical spring rigidity/horizontal spring rigidity), so they are only strained small vertically and exhibit large loading capacity. Consequently, the large-capacity table is manufactured easily at low cost. |
