Description

Extensometer method measure apparatus of youngs modulus
Technical field
This utility model belongs to teaching and experiment equipment field, is specifically related to a kind of extensometer method measure apparatus of youngs modulus.
Background technology
Young's modulus, it is along longitudinal elastic modelling quantity, is also the noun in the mechanics of materials.According to Hooke's law, at thing In the elastic limit of body, stress and strain is directly proportional, and ratio is referred to as the Young's modulus of material, and it is characterize material character one Individual physical quantity, is only dependent upon the physical property of material itself.The size mark of the Young's modulus rigidity of material, Young's modulus is more Greatly, it is less susceptible to deform upon.
Static method is taked in the detection of existing Young's modulus mostly, and static method refers to apply a constant bending on sample should Power, measures its elastic bending amount of deflection, or applies constant stretching (or compression) stress on sample, measure its elastic deformation Amount;Or calculate elastic modelling quantity according to stress and strain.Static method uses mostly optical lever and telescope measure Young's modulus, lack Point is that sample dosage is big, and instrument volume is big, and accuracy is low, it is impossible to replication.
Utility model content
In order to solve problems of the prior art, this utility model provides a kind of extensometer method Young's modulus and measures Instrument, this analyzer overcomes in prior art, it is necessary to use optical lever and telescopical complex device, the shortcomings such as accuracy is low.
The technical scheme that this utility model solution technical problem is used is as follows:
Extensometer method measure apparatus of youngs modulus, this analyzer includes support, upper grip, lower chuck, extensometer, pull sensing Device and force application apparatus;Described support is mesh type structure;Upper grip is arranged on the first crossbeam of described support;Lower chuck is arranged on On the second cross beam of described support;Force application apparatus is arranged on the 3rd crossbeam of described support;Tested two ends wiry are respectively It is fixed in upper grip and lower chuck;Extensometer is arranged on tested tinsel;The upper end of pulling force sensor is connected with lower chuck, Lower end is connected with force application apparatus;Pulling force sensor is executed downward power by force application apparatus, and pulling force sensor is measured tested tinsel and is subject to Power size, extensometer measures tested elongation size wiry.
The beneficial effects of the utility model are: this apparatus subject structure uses the design of portal frame formula, eliminates traditional Optical lever and the big parts of length-measured telescope two, it is simple to operation, technical merit is advanced, novel in design, domestically leading.
Accompanying drawing explanation
Fig. 1 this utility model extensometer method measure apparatus of youngs modulus front view.
Fig. 2 this utility model extensometer method measure apparatus of youngs modulus main frame and digital display represent intention.
In figure: 1, upper grip, 2, tested tinsel, 3, support, 4, lower chuck, 5, second cross beam, 6, afterburning handwheel, 7, can Adjust footing, 8, base platform, the 9, the 3rd crossbeam, 10, pulling force sensor, 11, first crossbeam, 12, extensometer 13, digital display meter.
Detailed description of the invention
With embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, extensometer method measure apparatus of youngs modulus, this analyzer includes support 3, upper grip 1, lower folder 4, extensometer 13, pulling force sensor 10 and afterburning handwheel 6;Described support 3 is mesh type structure;Upper grip 1 is arranged on described On the first crossbeam 11 of frame 3;Lower chuck 4 is arranged on the second cross beam 5 of described support 3;Afterburning handwheel 6 is arranged on described support On 3rd crossbeam 9 of 3;The two ends of tested tinsel 2 are separately fixed in upper grip 1 and lower chuck 4;Extensometer 13 is arranged on institute State on the tested tinsel 2 between the first crossbeam 11 of support 3 and second cross beam 5;The upper end of pulling force sensor 10 is with lower chuck 4 even Connecing, lower end is connected with afterburning handwheel 6;Adjustable bottom feet 7 is installed on the base platform 8 of support 3, whether adjusts measure apparatus of youngs modulus In the horizontal plane.Rotating afterburning handwheel 6, rotate along bolt, bolt moves downward, and pulling force sensor 10 is applied downward power, Tested tinsel 2 produces deformation, and now, pulling force sensor 10 measures the stress size of tested tinsel 2, and extensometer 13 measures quilt Survey the elongation size of tinsel 2.Measurement data is passed through data line transfer to digital display meter by pulling force sensor 10 and extensometer 13 On, digital display meter is calculated the Young's modulus of tested tinsel 2 by the computing formula E=F L/S Δ L of Young's modulus;Wherein F For the value of thrust of tested tinsel 2, L is the extensometer gage length value of tested tinsel 2, the cross section product value of the tested tinsel of S 2, Δ L is the deformation values of the extensometer of tested tinsel 2.
Important technological parameters of the present utility model:
1, maximum pull (N): 30
2, pulling force display resolution value (N): 0.001
3, extensometer gage length (mm): 100
Extensometer range (mm): 5
4, extensometer deformation display resolution value (mm): 0.001
5, steel wire (mm): L=400 Φ=0.50
Steel wire (mm): L=400 Φ=0.80.
