PROBLEM TO BE SOLVED: To provide a three-dimensional model construction method for woven fabric and a three-dimensional model construction device for the woven fabric, for simulating deformation of the woven fabric when processing the woven fabric into a product shape.;SOLUTION: All the possible deformation conditions are applied to a given woven fabric standard in advance to create a database of two-axis deformation behavior, a target curved surface is converted into a Bezier curved surface from read CAD data of the product shape, and devided according to a division rule of the Bezier curved surface in each size of a woven fabric texture one cycle, a curvature in an area center point and a path length of a boundary line of each area is calculated to a minute area, a three-dimensional model is created by use of forward calculation technique, and a deformation state of each the minute portion is calculated. A result is integrated to obtain a distortion amount distribution of the whole curved surface.;COPYRIGHT: (C)2009,JPO&INPIT
