20110239771 | TRIAXIAL VIBRATION COMPOSITE TESTING APPARATUS - A triaxial vibration composite testing apparatus including a working tabletop, wherein the second axial vibration transmission mechanism in the horizontal X axial direction and the third axial vibration transmission mechanism in the horizontal Y axial direction are both cross linear guide pairs; the first axial vibration transmission mechanism in the perpendicular Z axial direction includes an upper and a lower clamps and a central panel, the upper and the lower clamps being horizontally opposite to each other up and down, the central panel being positioned between the upper and the lower clamps, the upper and the lower clamps oppositely clamping the central panel; a gap fit between the lower surface of the upper clamp and the upper surface of the central panel forms an upper fit plane, and a gap fit between the upper surface of the lower clamp and the lower surface of the central panel a lower fit plane; and the high pressure oil is pumped into the upper fit plane gap and the lower fit plane gap to form a hydrostatic oil film, thus constituting a hydrostatic plane bearing mechanism. | 10-06-2011 |
