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.
