Abstract
A two-sided friction device used for shear elasticity modulus of a rubber support comprises a basic layer. The upper and the lower two surfaces of the basic layer are fixedly connected with a friction material layer through a bonding material layer. Preferably, the basic layer adopts a fiber paper layer and the friction material layer adopts a sand layer. The two-sided friction device with simple structure and good anti-slide effect improves the anti-slide capacity of a test piece, ensures that the test piece cannot slide relatively, and also ensures the accuracy of the test data. In addition, the basic layer, the bonding material layer and the friction material layer are all made of materials sold on the market at lower costs, so that the two-sided friction device has the advantages of simple production technique, low manufacturing cost, light weight, convenient installation and replacement, test cost conservation, and improved test efficiency.
Description
Technical field
The utility model relates to a kind of test aid, particularly a kind of rubber support shear modulus test both surface friction device.
Background technology
At present, the operating process of carrying out the test of rubber support shear modulus is: on the loading plate of testing machine, it is good that sample and middle steel arm-tie are pressed the double shear combining and configuring, make the axis of symmetry of sample and middle steel arm-tie and testing machine loading plate central axis on same vertical plane, and guarantee that precision should be less than 1% test specimen minor face size; Then, apply the vertical force of a 10MPa, keeping applying horizontal shear under the constant situation of this vertical force to sample.In applying the process of horizontal shear, need to guarantee that relative slip does not take place test specimen.For preventing skidding, should be pasting the steel friction plate that costs an arm and a leg on loading plate and the middle steel arm-tie up and down, with the accuracy of guaranteeing to test.But the friction plate that present testing machine manufacturer provides can't play the antiskid effect, testing crew often finds that in process of the test test specimen obviously moves, influenced the accuracy of test figure, sometimes even the situation that test specimen skids off testing machine takes place, test can't have been carried out; If buy the steel friction plate voluntarily, cost an arm and a leg and need and often change, test efficiency hangs down has increased experimentation cost simultaneously.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of rubber support shear modulus test simple in structure, low cost of manufacture and uses the both surface friction device, can prevent that test specimen from taking place to slide relatively in process of the test, has guaranteed the measuring accuracy of test; Simultaneously in process of the test, need not often to change expensive steel friction plate, saved experimentation cost, improved test efficiency.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the both surface friction device is used in a kind of rubber support shear modulus test, comprises basic unit, and basic unit's upper and lower surface is fixedlyed connected with friction material layer by layer of adhesive material.
Basic unit is preferably fiber paper.
Friction material layer is preferably layer of sand.
The rubber support shear modulus test both surface friction device that the utility model provides, owing to form by basic unit, layer of adhesive material and friction material layer, simple in structure, good antiskid effect, improved the skid resistance of test specimen, guarantee that relative slippage does not take place test specimen, guaranteed the accuracy of test figure; The manufacturing materials of basic unit, layer of adhesive material and friction material layer is selected commercially available and lower-cost material, and production technology is simple, low cost of manufacture, and is in light weight, is convenient to install and replaces, and has saved experimentation cost, has improved test efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the synoptic diagram that the utility model is applied to the test of rubber support shear modulus.
Embodiment
As shown in Figure 1, the utility model comprises basic unit 3, and basic unit's 3 upper and lower surfaces are fixedlyed connected with friction material layer 1 by layer of adhesive material 2.
Basic unit 3 is preferably fiber paper.
The tasteless bonding agent of layer of adhesive material 2 preferred employings is made, as aerodux or epoxy adhesive.
Friction material layer 1 is preferably layer of sand, and preferably adopting the sandstone modulus of fineness is 3.0-2.3, and the medium sand of mean grain size 0.5-0.35mm is made.
During making, at first the glue brush is obtained layer of adhesive material 2 at the upper and lower surface of fiber paper, again sand is sprinkled upon on the layer of adhesive material 2 uniformly, treat just to obtain rubber support shear modulus test both surface friction device behind layer of adhesive material 2 bone dries.
As shown in Figure 2, during test, between bearing plate on the testing machine 4 and following loading plate 7, it is good that bearing sample 5 and middle steel arm-tie 6 are pressed the double shear combining and configuring, make the last bearing plate 4 of the axis of symmetry of bearing sample 5 and middle steel arm-tie 6 and testing machine and following loading plate 7 central axis on same vertical plane, and the assurance precision should be less than 1% test specimen minor face size; Need when configuration bearing sample 5 and middle steel arm-tie 68 four top and bottom that are layered on every bearing sample respectively of both surface friction device, both surface friction device 8 one sides are contacted with bearing sample 5, both surface friction device 8 another sides contact with steel friction plate 9, fall top board again, can begin test.
