Specific embodiment
The invention discloses a kind of bursting strengthening flexible composite Bursting Properties for testing textile/textile structural
Device, the site of engagement in the middle of two plate clamps up and down in this device adopts special structure design, also adopts between upper lower clamp
Reinforced further with three sets of bolt and nuts, this design significantly improves and strengthens flexibility again to textile to be measured/textile structural
The clamping fastness of condensation material, reduces the Relative sliding between sample to be tested and fixture and textile structural in burst testing test process
Middle yarn withdrawing, improves accuracy and the reliability of bursting test；In addition, this fixture is also designed to and lower end test equipment
The pilot pin being attached, increases the stability in bursting test process further.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is retouched in detail
State it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the present invention
In embodiment, the every other enforcement that those of ordinary skill in the art are obtained on the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
As shown in Figures 6 to 9, a kind of thorn cone i, described thorn cone i adopt platypelloid type or pyramid type or dome-type or sticker type.
The diameter change scope of described thorn cone i is 5mm-20mm.This thorn cone i adopts multiple geometry designs, and simulation difference uses ring
Under border, textile/textile structural strengthens the bursting damage type of flexible composite, expands the suitability of this device.
As shown in Figures 1 to 5, a kind of fixture c, it includes upper fixture 1 and lower clamp 2, uses between described upper lower clamp
Tongue and groove coordinates.Tongue and groove cooperation may insure textile/textile structural composite materials do not produce in load bearing process sliding with
And the withdrawing of yarn is it is ensured that the accuracy of experimental result.
Described fixture c's is generally circular in shape, and described circular fixture interior diameter excursion is 50mm-150mm.The present invention
The shape of fixture is designed as circle, primarily to ensure that fabric accomplishes the load in all directions when bearing bursting load as far as possible
Lotus is essentially identical, it is to avoid the situation of stress concentration.Fixture disk interior diameter is the Validity Test region of sample to be tested, inside and outside
Difference between diameter is clamped region for testing sample, and the size of this clamping zone directly determines whether sample is effectively held
Hold.Therefore, can effectively grip in test process for ensureing sample, the size of this clamping zone should control in 30mm-50mm
Within.
In order to ensure the close engagement between upper lower clamp, upper and lower two fixtures also carry out positioning using bolt 3 and reinforce,
Reinforce bolt 3 and can adopt two kinds of methods for designing：
1. the first is to carry out equidistant fixation, the letter of the method Design of Dies on fixture disk using three sets of bolt and nuts
Just quick, only need in test sample preparation process perforate be carried out on sample to facilitate passing through of reinforcing bolt, such as Fig. 3 and figure
Shown in 4.
2. second is using outer fixation, and particularly the mode of three sets of external fixing bolts carries out equidistant fixation, should
Method may insure the structural intergrity of fabric sample, it is to avoid local failure, as shown in Figures 1 and 2.
Sample to be tested center fixing device (hollow drill bit) is equipped with described fixture c；Existed with the loading position guaranteeing to pierce cone
The middle part of testing sample, in order to avoid cannot determine the center of fabric in bursting test process, causes to test personal error.
A kind of bursting device, it includes described thorn cone i and described fixture c, and described bursting device also includes testing stand
A, the stress being connected with bursting chuck d located at the support h on testing stand, the base b on testing stand a, bursting chuck d, should
Become sensor e, high-speed camera f, hydraulic servo motor g, described hydraulic servo motor g is connected with bursting chuck d, described bursting
Chuck d is connected with thorn cone i.
This bursting device provides different jig Design, to adapt to different testing sample demands；The serial shape of thorn cone
Shape is mainly designed to strengthen the bursting process of flexible composite to simulate textile in different use environments/textile structural.
The velocity interval that in described bursting device, thorn cone declines is 0.1mm-500m/s, and the range of the bursting strength of described bursting device sets
It is calculated as 0.1N-20000N.
Wherein the jaw in bursting chuck adopts trapezoidal design, and with the carrying out of bursting process, bursting strength increases, this
The jaw of trapezoidal design can be continuously increased the curable grip to chuck, prevents from leading to thorn cone and bursting chuck because bursting strength is excessive
Between produce sliding, and then affect bursting test result accuracy.
The addition of high-speed camera can carry out real time record shooting to the surface of sample to be tested j in bursting experimentation,
Observe deformation, the generation of breakdown point and extension during bursting for the fabric.Especially during high speed bursting, this experiment
Data can provide effective foundation for the analysis of bursting damage mechanisms.
Compared with prior art, the invention has the beneficial effects as follows：
