DEVICE FOR TESTING deformation properties of textile fabrics under multiaxial LOADS

摘要

The invention relates to the textile industry, in particular, to a device for testing the deformation properties of textile fabrics with multicycle loads. The device allows to measure the deformation and the tensile force of the sample under multiaxial textile fabric loads separately for 16 directions to obtain linear and pie charts as in polutsiklovyh and at multicycle test. These tests make it possible to analyze the capacity for shaping and operational capabilities of textile fabrics, used to produce a special, protective clothing, and composite materials. The device comprises a stationary housing with a movable platform actuator biasing means in the form of a hemispherical pusher cam vibroprivody, removable clamping device mounted on a mobile platform and consisting of 16 clips disposed around the pusher, each of which has a slider with locking jaws coupled to the strain gauge sensor beam type. Sample webs cut into a circle, is clamped simultaneously at all times with uniform tension. The hemispherical plunger, moving perpendicular to the plane of the sample, it pushes the keeper, the sliders by the elasticity of the material being tested are moving to the center of the circle. The force exerted on the slider, and moving strain gage is fixed. Surrenders electrical signal to the computer, displaying data on the deformation properties of the material: elongation, strength, elasticity, compressive strength along each axis separately and integration in a pie chart, 3 Fig.
