Problems solved by technology

Moreover, the measurement index is single and the measurement mode is single. For example, the marble bursting test machine specified in the existing national standards is only a single test of the bursting strength of textile materials (GB / T8878-2002 "Balloon Bursting Strength Test"), which cannot Perform tension, compression and puncture measurements

Embodiment 1

[0050] Embodiment 1, the induced force-displacement curve of the double-ended sensor under tension.

[0051] By adopting the device and method of the present invention, force sensors 4 and small load suspension clips 51 are installed on the upper beam 11 and the middle beam 2, and the middle beam 11 is driven to the set displacement position; a carbon fiber sample of a certain length is prepared on the bottom plate 3, The two ends of the sample are respectively clamped by the small load hanging clamps 51 on the middle beam 2 and the upper beam 11; the clamping distance (20mm), the tensile speed (10mm / min) and the one-time breaking mode are selected by computer operation, Start the program software to drive the center beam 2 to move vertically downwards to complete the tensile test. Since the force sensors 4 are installed on the upper beam 11 and the middle beam 2, two force-displacement curves can be obtained correspondingly. After the carbon fiber is stretched and broken, th...

Embodiment 2

[0053] Embodiment 2, the induced force-displacement curve of the double-ended sensor under compression.

[0054] Adopt the device and method of the present invention, install force sensor 4 and heavy-duty hanging clip 52 on the middle beam 2 and the base plate 3, and drive the middle beam 2 to the set displacement position; cut the worsted wool whose length×width is 8cm×4cm Fabric sample; the two ends of the sample are respectively clamped by the heavy-duty hanging clamps 52 on the middle beam 2 and the bottom plate 3; the clamping distance (3mm), compression moving speed (1mm / min) and constant load are selected by computer operation In the reciprocating mode, the program software drives the middle girder 2 to move vertically downward to complete the compression experiment. The structural diagram of the compression device is shown in Figure 5 shown. Since the force sensor 4 is installed on both the center beam 2 and the bottom plate 3, two force-displacement cycle curves can...

Embodiment 3

[0055] Embodiment 3, single-ended sensor induction force-displacement curve under bursting action.

[0056] Adopt the device and method of the present invention, install the force sensor 4 on the center beam 2 and drive the center beam 2 to the set displacement position; insert the round end push rod 531 into the fixed base 538 on the upper beam 11 and fix it; the cutting diameter is 5cm Worsted woolen fabric sample, on the sample preparation table 32 on the bottom plate 3, fix this fabric sample with the top thorn sample holder 54, then the top thorn sample holder 54 is fixed on the middle beam 2; by computer Operate the selected moving speed (10mm / min) and one-time bursting mode, and the program software drives the center beam 2 to move vertically upwards to complete the bursting experiment. After the fabric sample is broken, the micro-motor drives the center beam 2 back to its original position, and the test is completed. The structure diagram of the breaking device is as ...

Abstract

The invention relates to a combining ability and displacement measuring method and device of textile materials containing fiber, yarn, cloth, film and composite material, by which combining ability-displacement curve and stress-strain carve and measurement of associative characteristic value are obtained. The measuring device is consisted of multi-functional clamper suitable for textile materials, frame top beam, middle beam and under beam where sensor and multi-functional clamper can be installed, driving element controlled by middle beam, force and displacement signal collection card And computer with modules of program control and data processing. The invention includes the following properties that force sensor can be fitted on anywhere of the under beam, which can measure force value of moving terminal, and its structure is simple, operation is convenient and multi-functional clamper can be replaced fast and conveniently.

Description

Technical field: [0001] The invention belongs to the technical field of textile precision measuring instruments, and relates to a combined force-displacement measurement method and device for stretching, compression, bursting and puncturing of textile materials (fibers, yarns, fabrics, films and composite materials thereof). Simultaneous and combined measurement and evaluation of tensile, compression, burst and puncture mechanical properties of textile materials. Background technique: [0002] The mechanical properties of textile materials (fibers, yarns, fabrics, films and their composites) such as tension, compression, bursting and puncturing play a vital role in the forming and processing of textiles, clothing and industrial use, both affecting The tensile and compressive properties of non-manufacturing cloths (including paper, filter cloths, geotextiles, and medical and sanitary cloths, etc.) determine the properties of woven and knitted fabrics (including aerospace clot...
