Embodiment Construction

[0008] As shown in the drawings, the present invention includes: a flange 5, a pressurized bolt 3 and a pressure sensor 1, and the laminated rubber bearing 4 is fixed on the action plate 6 and the side wall 7 of the MTS fatigue testing machine 2 through the flange 5 Between, and through the pressure bolt 3 to keep the action plate 6 and the side wall 7 in a compressed state, the pressure exerted by the pressure bolt 3 is monitored by the pressure sensor 1 . The flange plate 5 and the action plate 6 are fixed by bolts 8 , and are fixed to the side wall 7 by screw nuts 8 .

[0009] When in use, the laminated rubber bearing 4 is first pressurized by the pressure bolt 3, and the pressure signal is obtained by the pressure sensor 1. When the pressure reaches a certain level, the laminated rubber bearing 4 is subjected to compression shear fatigue. performance test, therefore, the present invention realizes compression-shear fatigue bidirectional loading under compression.

Abstract

The invention discloses a lapping rubber support high main pressure shearing fatigue testing device which comprises flange, pressing bolt and pressure sensor, the lapping rubber support is fixed on the flange between the motion plate and side wall and is pressed tightly with the pressing bolt the pressing force of which is monitoring by the sensor. The invention acquires the dual direction shearing fatigue loading when adding pressure, and is able to perform the test with normal test machine. The invention is of simple structure and operation.

Description

technical field [0001] The invention relates to a compression-shear fatigue test device for laminated rubber bearings. Background technique [0002] Laminated rubber bearings are mainly used in the anti-seismic aspects of building structures, and have lower requirements on fatigue performance. At home and abroad, only the large-strain low-cycle fatigue performance of rubber bearings is tested. In order to apply laminated rubber bearings to anti-ice and vibration isolation of offshore platforms, it is necessary to conduct small-strain high-cycle fatigue performance tests on laminated rubber bearings. At present, the high-cycle fatigue performance test of laminated rubber bearings has not been reported, and the high-cycle compression-shear fatigue test of laminated rubber vibration-isolation bearings has not been carried out in China. Therefore, the special test equipment in this respect at home and abroad is still blank. Contents of the invention [0003] In view of the ...
