摘要
为更好地了解平纹、斜纹和经面缎纹3种基本组织纯棉机织物抵抗外力拉伸变形的能力,在实际测量织物结构参数的基础上,提出一种评价和预测机织物拉伸性能的方法;借助专业纺织建模软件Texgen建立织物三维细观模型;利用有限元软件ABAQUS,依据织物拉伸环境设置材料属性、相互作用和边界条件等计算模型数值解;通过织物拉伸强力测试实验验证数值模拟结果的有效性。结果表明:平纹织物、斜纹织物和经面缎纹织物拉伸应力、应变模拟结果与实验测试结果差异率均在6%以内;在原料、经纬纱密度和捻度、织物经纬密都相同的条件下,平纹织物抵抗外力变形的能力更强。
In order to better understand the resisting external tensile deformation capability of the plain weave,twill and warp satin three-elementary cotton woven fabrics,a method for evaluating and predicting the tensile properties of woven fabrics was proposed. On the basis of the measured fabric structure parameters,a three-dimensional textile microscopic model was established by a professional textile modeling software Texgen. The numerical solution of the model was calculated using finite element software ABAQUS,setting material properties,interaction and boundary conditions according to the fabric stretching environment. The effectiveness of the numerical simulation was verified by the tensile test of fabric. The results show that the difference between simulation results and experimental test results on tensile stress and strain of plain weave fabric,twill fabric and warp satin fabric is within 6%. Plain weave has stronger resistance to external deformation under the same conditions of raw material,warp and weft yarn density,twist and warp and weft density.
