Three-dimensional simulation of warp knitted axial fabric for bulletproof

为了提高防弹材料的抗冲击性,对经编衬纬闪避垫纱形成的衬经与全幅衬纬纱线编织组合的经编轴向织物进行分析并对其进行三维仿真研究。通过建立通用的垫纱数码数学模型和穿纱数学模型及线圈基本模型来研究防弹用经编轴向织物的编织原理和结构特点,并根据建立的垫纱数码数学模型对该类防弹用经编轴向织物中的闪避垫纱位置进行判断,从而对产生闪避垫纱的位置进行赋值,然后再对衬纬梳栉进行受力分析,得出与实物相符的偏移量。研究结果表明,采用JavaScript和C#作为计算机程序设计语言实现了该类防弹用经编轴向织物的仿真,可为防弹用经编轴向织物的结构探究与力学分析提供快捷有效的方法。

In order to improve the impact resistance of bulletproof materials,the warp-knitted axial fabric formed by the warp-knitted inlay yarn and the full-width inlay yarn is analyzed and three-dimensional simulation is carried out.The weaving principle and structural characteristics of warp-knitted axial fabrics for bulletproof are studied by establishing a general digital mathematical model of padding yarn,a mathematical model of threading yarn and a basic model of coil.According to the established digital mathematical model of padding yarn,the position of dodging padding yarn in this kind of warp-knitted axial fabrics for bulletproof is judged,so as to assign the position of dodging padding yarn,and then the force analysis of the weft insertion guide bar is carried out to obtain the offset consistent with the object.The research results show that JavaScript and C#are used as computer programming languages to realize the simulation of this kind of bulletproof warp-knitted axial fabric,which provides a quick and effective method for the structure exploration and mechanical analysis of bulletproof warp-knitted axial fabric.
