摘　　要：为加快贯穿正交机织物结构的三维建模过程,在交织规律的基础上以纬纱层数、纬纱直径、地经直径、接结经直径4个独立参数,建立了贯穿正交机织物结构单元的几何关系及其三维模型。根据独立参数给出了理想状态下层间纬纱、地经纱线轴线间距,同层内相邻纬纱、地经纱轴线间距,相邻接结经纬向间距,以及结构单元纬向宽度、经向长度和厚度的计算方法。运用3ds Max软件的Maxscript脚本语言编程方法,通过输入纱线直径、纬纱层数等参数,由纱线型值点坐标构建SplineShape类对象,分别构建出纬纱层、地经层及接结经,从而实现了该类织物结构的参数化三维建模。In order to accelerate the three-dimensional modeling process of through-thickness orthogonal woven fabric structure,based on the interweaving rule,four independent parameters,including the number of weft layers,the weft diameter,the ground-warp diameter,and the binder-warp diameter,were utilized to establish the geometric relationships and three-dimensional models of the structure unit of through-thickness orthogonal woven fabric.According to the independent parameters,the calculation method of the axial spacing between layers of weft and ground-warp,the distance between weft in the same layer and the axis of the warp in the same layer,the distance between binder-warp in the weft direction,and the width,length and height of the structure unit were given under the ideal state.Using the 3ds Max software′s Maxscript scripting language programming method,by inputting yarn diameters and layers of weft yarns,the SplineShape class objects were constructed from data point coordinates of yarns,and the weft layer,the ground-warp layer and the binder-warp were constructed,respectively,thereby realizing parametric three-dimensional modeling of this kind of woven fabric.
