摘要/Abstract

摘要： 根据纱罗组织结构特点提出三维绞织机织物,为满足织物结构构建的精准性,利用织物层数、纬纱列数、经纬纱个数等参数进行表征;根据机织造工艺情况与织物结构参数,对经纱绞织规律研究提出经纱系统规律参数方程,使用Matlab构建经纱曲线获取型值点,通过三次B样条曲线控制点建立经纱系统模型,提出纬纱系统结构参数方程,完成织物几何模型;利用Solidworks构建织物仿真模型。

Abstract: According to the characteristics of the leno structure, a three-dimensional twist loom fabric is proposed. In order to meet the accuracy and authenticity of the three-dimensional twist loom fabric construction, the parameters of the fabric are characterized by the number of layers, the number of weft rows, the number of warp and weft threads, and the vertical weft distance organization. Then, according to the weaving process and fabric structure parameters, the warp yarn skeining law is studied to propose the law parameters of the warp system. Matlab is used to construct the warp curve to obtain the shape point. The shape point is used to obtain the control point. The cubic B-spline curve control point is used. The warp yarn system model is established, the structural parameter equations of the weft yarn system are proposed, the yarn section shape parameter equations are constructed, and the fabric geometric model is completed. Finally, Solidworks was used to construct a fabric simulation model to obtain a three-dimensional model of the fabric. The volume content of the unit cell fibers was calculated, which can be used for fabric performance analysis to achieve the designable purpose of composite material performance.

Key words: three-dimensional twisted woven fabric, fabric structure, geometric model, simulation, composites
