Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.
[0028] refer to Figure 1-5 , a dynamic compression-shear testing machine device, comprising a base 8, the two ends of the base 8 are fixed with a reaction force support 3, the upper end of the reaction force support 3 is fixed on the crossbeam 2, and the upper ends of the two reaction force support 3 are jointly fixed with a crossbeam 2. The vertical oil cylinder 1 is fixed on the crossbeam 2. Two reaction force supports 3 and the vertical oil cylinder 1 are installed on top of the host structure. There are two gaps at the upper and lower ends of the reaction force support 3, and built-in wedges 9 to eliminate the The gap between the beam 2 and the bas...

The invention discloses a dynamic compression-shear testing machine device which comprises a base, counter-force supports are fixed to the two ends of the base, each counter-force support is provided with four wedge block gap eliminating devices, a cross beam is fixed to the upper ends of the two counter-force supports, a vertical oil cylinder is fixed to the cross beam, and the wedge block gap eliminating devices are arranged on the vertical oil cylinder. The vertical pressure oil cylinder penetrates through the cross beam and extends to the lower end of the cross beam, an upper pressing plate is fixed to the tail end of a piston rod of the vertical pressure oil cylinder, guide rails are fixed to the two ends of the upper pressing plate, and wedge block anti-backlash devices are arranged on the four guide rails. A main engine structure with two counter-force supports and an upper oil cylinder is adopted, a linear guide rail is adopted at the lower end of a workbench, a swing shaft type shearing horizontal oil cylinder is adopted as a transverse shearing oil cylinder, and the shearing oil cylinder part is connected with the workbench in a hinged seat connection mode, so that the whole system forms a self-counter-force frame structure, gaps are eliminated to the maximum degree, and the working efficiency is improved. The horizontal load sensor and the vertical load sensor are prevented from being affected by different tangential forces in the test process, the test space is steplessly adjustable, test requirements of different heights are met, the whole machine is high in rigidity and small in deformation, stress and deformation generated by gaps in all directions are avoided, and it is guaranteed that measured data are accurate.
Description
technical field [0001] The invention relates to the technical field of dynamic compression-shear testing, in particular to a dynamic compression-shear testing machine device. Background technique [0002] The basic structure of the dynamic compression-shear testing machine is basically composed of columns, beams, bases, reaction frames, vertical cylinders and general shear cylinders. This equipment removes the columns and only uses reaction brackets, while the shear cylinders are replaced with swing shafts. Type shearing horizontal oil cylinder, and a wedge device is added in the horizontal and vertical directions of the whole machine to eliminate the gap. [0003] In order to solve the inaccurate needs of the detection results of the damage caused by the test of the sample (such as the shock-absorbing and isolating rubber bearing) due to the influence of the gap and the deformation stress, we invented this dynamic compression-shear test equipment according to the national s...
