Fabric three-dimensional pressure simulation test system

Abstract

The invention relates to a fabric three-dimensional pressure analog test system which is used for testing the dynamic contact pressure and the pressure attenuation characteristics of fabrics. The measuring principles of the invention refers to measuring dynamic clothing pressure during a process of fabric three-dimensional deformation by a pressing ball embedded with nine highly precise pressure sensors to press against the fabrics; the pressing ball is transmitted by a driving device, which can press against the fabrics for more than several thousand times so as to measure pressure fatigue. A pressure-displacement curve, a pressure-time curve and a pressure attenuation curve of each sensing point are respectively obtained by the processing of a computer. The analog test system of the invention has simple structure and convenient operation and is a testing instrument that can effectively and objectively evaluate fabric pressure performance.

Description

technical field

[0001] The invention belongs to the technical field of textile precision measuring instruments, in particular to a test system for contact pressure and pressure fatigue characteristics of fabrics (knitted fabrics, woven fabrics, non-woven fabrics and composite materials thereof), which is suitable for dynamic contact pressure and pressure attenuation characteristics of fabrics test. Background technique

[0002] Clothing pressure is one of the important indicators to evaluate the comfort, functionality and safety of pressure clothing. However, the research and development of clothing pressure testing institutions and testing instruments lag far behind the needs of scientific research, and there is no reasonable and unified testing standard. So far, there is no apparatus for fabric pressure testing similar to the present invention. Similar instruments with similar structures are: electronic bursting strength tester, which is mainly used to test the bursting ...
