Description
Technical field
The utility model relates to a kind of fracture test device, a kind of specifically adjustable angle formula composite rupture test unit.
Background technology
Tearing test is a kind of test that often will do in the engineering material test.
Compound in the world at present fracture test device is most widely used to be the Arcan device, yet its disadvantage is exactly to realize the test of 0 °, 15 °, 30 °, 45 °, 60 °, 75 °, 90 ° these 7 fixed angles, can not be applied to compound at any angle tearing test in the I/II MIXED MODE CRACK PROPAGATION and very important I type are arrived the accurate research that the II type is dominated transition angle problem.The device of domestic tearing test aspect to construction material is not seldom more seen the angle device of adjustable compound tearing test aspect arbitrarily.
The utility model technology is exactly constantly to sum up in concrete working practice, explores a kind of new fracture test device that proposes, and changes the defective that angle can not be adjusted arbitrarily in the prior art.
Summary of the invention
It is adjustable arbitrarily that goal of the invention of the present utility model just provides a kind of angle, can satisfy the requirement of I/II compound arbitrarily angled (crackle angle) tearing test, realizes the composite rupture test unit of the composite rupture performance test of construction material.
Realize that the technical solution of the utility model is such: adjustable angle formula composite rupture test unit, by great circle ring plate 12, mobile circular arc slotted vane 13 is formed, and concrete structure is respectively to offer 1,2,3,4, two fixed orifices 5,6 of four angle adjustment holes on two identical great circle ring plates 12; On two identical mobile circular arc slotted vanes 13, respectively offer two arc grooves 9,10, two test specimen fixed orifices 7, (8, on arc groove 9,10, be provided with bolt, this bolt links together great circle ring plate 12 and mobile circular arc slotted vane 13 by fixed orifice 5, (6) on the great circle ring plate 12.
Wherein, four angle adjustment holes (1,2,3,4), it entad arranges angle is that 30 degree are alternate, promptly alternate 30 degree are offered a hole; Two arc grooves (9,10), the pairing entad angle of its arc section are 30 degree, promptly are line entad with the bolt on test specimen fixed orifice and the arc groove, and then the move left and right of groove distance respectively is 15 to spend.
The beneficial effects of the utility model are, in the fracture property test of construction material, can finish the I/II Mixed Mode Crack from 0 ° to 90 ° between arbitrarily the test of crackle angle and very important I type to the accurate research of the leading transition angle of II type problem.Its mentality of designing is original, is easy to make, and is simple to operate, practical.Can be used as the annex bundle sale at random of Material Testing Machine, also can sell separately use.

Embodiment:
Below in conjunction with accompanying drawing of the present utility model, further describe technology implementation scheme of the present utility model.
Embodiment: adjustable angle formula composite rupture test unit, by great circle ring plate 12, mobile circular arc slotted vane 13 is formed, and concrete structure is respectively to offer 1,2,3,4, two fixed orifices 5,6 of four angle adjustment holes on two identical great circle ring plates 12; On two identical mobile circular arc slotted vanes 13, respectively offer two arc grooves 9,10, two test specimen fixed orifices 7, (8, on arc groove 9,10, be provided with bolt, this bolt links together great circle ring plate 12 and mobile circular arc slotted vane 13 by fixed orifice 5, (6) on the great circle ring plate 12.Wherein, four angle adjustment holes 1,2,3,4, it entad arranges angle is that 30 degree are alternate, promptly alternate 30 degree are offered a hole; Two arc grooves 9,10, the pairing entad angle of its arc section are 30 degree, promptly are line entad with the bolt on test specimen fixed orifice and the arc groove, and then the move left and right of groove distance respectively is 15 to spend.
The crackle angle is regulated and can be realized as follows arbitrarily:
At first, select the fixed angle of great circle ring plate---
Have the circular hole of four different angles to link to each other with testing machine on the great circle ring plate, these four holes can realize that the force direction that is subjected to of test specimen regulates between four integer angles of 0 °, 30 °, 60 °, 90 °.Crackle angle (θ) variation range that four circular holes can satisfy is as follows:
0≤θ≤15 ° selecting hole 1; 15 °≤θ≤45 ° selecting holes 2;
45 °≤θ≤75 ° selecting holes 3; 75 °≤θ≤90 ° selecting holes 4.
Secondly, calculate mobile circular arc slotted vane angle---
Mobile circular arc slotted vane can be realized-15 ° to+15 ° angular setting by rotating.Behind the circular hole on the requirement selection great circle ring plate of test crackle angle, by the required angle of fine setting realization of mobile circular arc slotted vane, formula is as follows:
Δθ＝θ-θ
i
In the formula: Δ θ represents the angle that moving-member will be adjusted ,-15 °≤Δ θ≤15 °;
θ represents the angle of testing requirements;
θ
iThe angle that realize in hole on the expression large circle, i=1,2,3,4.
Again, the crackle angle is regulated arbitrarily
By the hole on the great circle ring plate 1 (0 °), (30 ° in hole 2, hole 3 (60 °), the angular adjustment of hole 4 (90 °) and moving-member-15 ° to the angular adjustment in 15 ° of scopes cooperates, and can realize any adjusting of crackle angle between the I/II Mixed Mode Crack is from 0 ° to 90 °.Promptly
Fixed angle+moving-member the angle of any crackle angle θ=large circle parts
For example: the realization of crackle angle θ=11 ° arbitrarily: select hole 1 (0 °) to be connected with testing machine, mobile circular arc slotted vane is adjusted into 11 ° and gets final product.
The arbitrarily realization of crackle angle θ=70 °: select hole 3 (60 °) to be connected with testing machine, mobile circular arc slotted vane is adjusted into 10 ° and gets final product.
