摘要
为提前预测组织结构与经编贾卡鞋面材料舒适性的关系,以避免耗费大量的人力和时间,通过从鞋材不同功能区选取实验样品,借助建模软件Solidworks建立样品的三维结构几何模型,通过Ansys软件对该模型进行有限元分析的前处理及网格划分,然后将几何模型与空气流体动力学计算相结合,利用Fluent软件对织物的透气行为进行流体分析和数值模拟,最后将模拟结果与实验结果进行对比分析。结果表明:网眼组织的存在会增加鞋面材料的孔隙率进而增强鞋材的透气性能,同时,网眼处于反面的织物透气性大于网眼处于正面的织物透气性,模拟结果与实验结果相符,误差低于20%,因此利用数值模拟预测经编贾卡鞋材的透气性能是有效的。
Objective Air permeability affects the comfort of shue upper materials.Before making footwear products,it is necessary to test the air permeability of the sample upper materials.In order to study the influence of organizational structure on the air permeability of warp-knitted jacquard upper materials,it is necessary to explore a method for predicting the air permeability of warp-knitted jacquard upper materials.It is also necessary to verify the feasibility of data simulation research methods to improve the efficiency of shoe upper materials from design to production and then to final application,and reduce unnecessary waste of resources and time.Method The experimental samples were selected from different functional areas of the jacquard upper material.The front and back sides of the wear resistance zone were with dense surface and solid bottom(sample A),and the front and back sides of the breathable zone were with mesh surface and solid bottom(sample B1).sample B2 was obtained by adjusting the positive and negative orientation of sample B1.The fabric structure of each sample was observed by Nikon E100 microscope,and then the geometric model of the fabric sample structure was established by Solidworks three-dimensional modeling software.The geometric model of the sample was imported into Workbench finite element analysis software for model preprocessing and meshing,combined with geometric model and computational fluid dynamics.Fluent,a fluid analysis software,was adopted to calculate the permeability behavior of the fabric.In order to verify the feasibility of the simulation data,the permeability of the sample was tested by YG46IE-III automatic permeability meter,and the simulation results were compared with the experimental results.Results Speed cloud chart showed that the closer to the yarn model,the more blocked the airflow and the smaller the air flow rate.The pores in the coil were smaller than the gap at each longitudinal interval of the fabric,so the air flow rate between the pores in the coil was found
