Embodiment

At first see also Fig. 2, Fig. 3 and Fig. 5, closed shaking table of the present utility model is that to obtain test data, the relevant design reference as tester comprises via the vibration-testing machine vibration after placing shaking table fixing tester:

Shaking table 1, possesses a flat surface 2, cutter is established screw 3 on it, edge face 4 cutters around flat surface 2 outer rims are established several open-works 5, this edge face 4 forms a curved surface 6 in an end, edge curved surface 6 contracts downwards and forms a tubaeform contour body 7, be connected with tubaeform contour body 7 supportings by supporting rib 8 and ring-shaped bearing rib 9, and form first, two

spatial accommodations

10,11, cutter is provided with several open-works 12 on this tubaeform contour body 7, the inside that this ring-shaped bearing rib 9 surrounds forms several spacer ribs 13, this spacer ribs 13 connects with central shaft 14, by ring-shaped bearing rib 9, form number elongated slot 16 between spacer ribs 13 and

central shaft

14 and 15 four sides, platform bottom surface, cutter is established several screws 17 on the end face of spacer ribs 13 and central shaft 14, is connected between ring-shaped bearing rib 9 outer rims and the curved surface 6 on the four arc inclined-planes 18 that form five equilibrium on the tubaeform contour body 7 in addition;
