轴向经编针织物的设计与仿真

为了解决轴向经编针织物计算机辅助设计方面的不足并且最终实现其快速设计，本文针对轴向经编针织物的CAD设计与仿真功能进行了研究。在深入了解轴向经编针织物生产工艺的基础上，采用实验的方法测量了织物结构的尺寸，建立了轴向经编针织物的CAD设计模型，其中包括地组织模型和铺纬组织模型；重点研究并建立了轴向经编针织物的纱线与线圈的二维仿真模型，以及玻璃纤维衬纱、线圈的三维仿真模型；以Visual C++ 为开发工具，并且结合OpenGL（Open Graphics Library）图形库，最终在WKCAD4.0系统中实现了轴向经编针织物的CAD设计与仿真功能。

Design and simulation study of axial warp-knitted fabrics

In order to solve the problem of axial warp-knitted fabrics in computer aided design and realize fast designing,CAD design and simulation function of axial warp-knitted fabrics are studied.And on this basis an in-depth research of production process about axial warp-knitted fabrics is undertaken,the structural size of axial warp-knitted fabrics is measured,and CAD design models of these fabrics are built,including the ground structure model and weft structure model,with focuses on 2-D and 3-D simulation models of glass fiber yarn,loop,and laying-in yarn.With Visual C++ for development tools and combined with OpenGL graphics libraries,the CAD design and simulation functions of axial warp-knitted fabric are finally realized in the WKCAD4.0 system.
