Nine-axis linkage fatigue strong force test machine and test method thereof

Abstract

The invention provides a fatigue strong force test machine, in particular to a nine-axis linkage fatigue strong force test machine and a test method thereof. The nine-axis linkage fatigue strong forcetest machine comprises linear modules, a servo motor, a computer data processing module, a control panel, a force sensor, a left clamping device, a right clamping device and a friction rubber roller,wherein three groups of linear modules are arranged and respectively a left side linear module, a middle linear module and a right side linear module; through being driven by the three groups of linear modules, the left and right clamping devices and the friction rubber roller can do unidirectional movement, universal movement and point movement in the X, Y and Z directions. The fatigue strong force test machine provided by the invention can use the nine-axis linkage mode; the three groups of (left, middle and right) linear modules can control the left and right clamping devices and the friction rubber roller to respectively do free movement in the three-dimensional space, so that the simulation of the irregular friction of textile in the use process can be really realized; the free movement modes of clothes worn on the body and external friction articles can be simulated.

Description

technical field [0001] The invention relates to a fatigue strength testing machine, in particular to a nine-axis linkage fatigue strength testing machine and a testing method thereof. technical background [0002] As an indispensable part of people's daily life, textiles will constantly rub, stretch, twist, and bend with the skin or the outside world during use. Under the interaction with other materials, such phenomena as pilling, exposure of spandex filaments, fiber breakage, bagging and arching will gradually appear, and this change seriously affects the comfort and aesthetics of fabrics or clothing. For example, stretch garments made of stretch fabrics will lose elasticity in the weft direction after repeated wearing and washing. And it cannot be restored, which seriously affects the aesthetics of consumers. At the same time, the elastic fabric loses its elasticity. In severe cases, the fabric will foam and arch, resulting in serious deformation of the ready-made garmen...

AI Technical Summary

Problems solved by technology

For example, elastic garments made of elastic fabrics will lose elasticity in the weft direction after repeated wearing and washing. And it cannot be restored, which seriously affects the aesthetics of consumers. At the same time, the elastic fabric loses its elasticity. In severe cases, the fabric will blister and arch, resulting in serious deformation of the garment and cannot be worn.
