采用ABAQUS的粘胶机织物拉伸力学性能仿真

为预测织物拉伸性能，采用有限元方法对织物拉伸力学进行数值模拟分析。在实测织物几何结构参数的基础上，借助纺织建模软件Texgen建立了织物模型；利用有限元软件ABAQUS模拟织物拉伸环境，设置材料属性、相互作用和边界条件，得到织物拉伸变形后应力分布云图以及拉伸时应力—应变曲线图等数值模拟结果；最后通过织物拉伸强力测试实验对数值模拟结果进行了验证。结果显示：模拟所得应力—应变曲线和实验所得拉力—伸长曲线上升趋势大致相同；模拟所得最大拉伸应力与实验所得拉伸应力平均误差为3.03%，证明了采用ABAQUS有限元软件模拟粘胶织物拉伸力学性能的是可行的。

Tensile mechanical properties simulation ofviscose woven fabrics based on ABAQUS

In order to predict fabric tensile properties, the finite element method was used to analyze the tensile mechanics of the fabric. Based on the geometric structure parameters of the fabric, the fabric model was established by using the textile modeling software Texgen, and the material properties, interaction and boundary conditions were set in the finite element software ABAQUS to simulate the tensile mechanical properties of the fabric, strain - strain curve and stress distribution after extension and deformation. Finally, the simulation results were verified by the tensile strength test of the fabric. The results show that the simulated strain-strain curve is roughly the same as the tensile-elongation curve of the experiment. The error between maximum tensile stress and the experimental tensile stress is 3.03%, which proves that ABAQUS finite element software can simulate the reliability of viscose fabric tensile mechanical properties.
