As shown in Figure 3, further, the present embodiment also comprises significant target spot 11, and described significant target spot 11 is six, can move up and down on crossbeam 2 and be evenly equipped with three significant target spots 11, can move left and right on crossbeam 3 and be evenly equipped with three significant target spots 11.6 significant target spots of high precision guarantee that arbitrary neighborhood target spot is homocentric.Lateral marker target spot and longitudinal place, significant target spot center of circle line orthogonal.Test macro reference frame is set up when these significant target spots can be used for fold test.
As shown in Figure 4 and Figure 6, the described crossbeam 2 that moves up and down maybe can move left and right crossbeam 3 and is made up of pole 21 and two clamping plate 22, and pole 21 is arranged in two clamping plate 22.Thinfilms is clamped with clamping plate on pole again, is convenient to the adjustment of film initial flatness.
As shown in figure 5 and figure 7, the described crossbeam 2 that moves up and down maybe can move left and right crossbeam 3 and is made up of two stripe board, two stripe board is equipped with protruding 23 and groove 24, and the projection 23 in a described stripe board and the groove 24 in another stripe board match.Projection in above-mentioned such two stripe board and groove are called antisymmetry notch.Film can be avoided maybe can to move left and right crossbeam 3 changing of the relative positions slippage crossbeam 2 can be moved up and down.
Embodiment 2
As shown in Figure 8 and Figure 9, the difference of the present embodiment and embodiment 1 is, add two with the mix-loaded parts 30 by crossbeam 31, a clock gauge 7 and two two exchange devices, described two mix-loaded parts 30 are arranged symmetrically with, mix-loaded parts 30 are arranged in the vertical rod 1 of side by two exchange devices, another mix-loaded parts 30 are arranged in the vertical rod 1 of opposite side by another two exchange device, the clock gauge 7 of described increase is fixed on base 9 with clock gauge 7 symmetry formerly, clock gauge contact pilotage 6 on the clock gauge 7 of described increase contacts with the other end that can move left and right crossbeam 3, in described vertical rod 1 and by crossbeam 31 is equipped with scale.
Two vertical rods of the present embodiment and the horizontal mix-loaded parts crossbeam that newly increases are provided with scale, for leveling and load displacement reading is set.Two vertical rods, apart from outside be arrangeding in parallel, also should ensure depth of parallelism when moving up and down cross beam movement, ensure level.Therefore, two vertical rods also have two effects: (1) learns the vertical displacement that can move up and down crossbeam; (2) levelness that can move up and down crossbeam is learnt.Thus the displacement (or load) that can move left and right crossbeam can be obtained.In addition, the load measurement that two clock gauges (or load transducer) are convenient to biaxial loadings is laid about the moved left and right crossbeam for bottom.
The present embodiment can realize pure extension (unidirectional, two-way), pure shear (unidirectional, two-way) and draw cutting coupling (unidirectional, two-way) loading and face intort.What a few class was commonly used go out, and pleat experiment loading form all can utilize the proving installation of the present embodiment to realize.
Two exchange devices described in the present embodiment are made up of the horizontal sleeve pipe 2 33 of the horizontal sleeve pipe 1 with thumb screw and band thumb screw, together with the horizontal sleeve pipe 1 of described band thumb screw is vertically fixed on mutually with the horizontal sleeve pipe 2 33 of band thumb screw, horizontal sleeve pipe 2 33 with thumb screw is enclosed within vertical rod 1, and the horizontal sleeve pipe 1 of band thumb screw is enclosed within by crossbeam 31.(such structure is also applicable to can move up and down crossbeam 2 and can move left and right crossbeam 3)
The present embodiment can realize horizontal addload or laterally provide pretension to film.Can realize moving up and down, and work as side upwards, when opposite side moves down, realization be sheared and loads.Load when this frock level utilizes the moved left and right crossbeam of bottom to carry out shearing, and when vertical direction utilizes mix-loaded parts to carry out shearing loading, if both shear directions in the same way, produce and the torsion of test specimen is loaded, if both shear directions are contrary, then double direction shear produced to test specimen and load.
The above; be only the present invention's preferably embodiment; these embodiments are all based on the different implementations under general idea of the present invention; and protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
