细编穿刺织物矩阵刚度优化设计的研究

Optimization Design for Stiffness of Needle Matrix Based on Fine-Weave Piercing

机织布在穿刺过程中与钢针矩阵之间产生相互作用,该作用使钢针矩阵产生有害变形,并对布层造成损伤。因此,基于钢针矩阵刚度优化设计的原理,建立优化设计的模型、合理地选择钢针矩阵结构参数,可有效控制穿刺过程中钢针矩阵的变形及布层的损伤,为改进细编穿刺工艺和优化织物结构提供了理论依据。

The interaction between orthogonal laminated woven fabrics and steel needle matrix during the pierc process can cause the injurious deformation of steel needle matrix and permanent damage of fabrics. So, based on lng the principle of optimization design for the stiffness of needle matrix, the structural parameters affecting the stiffness were analyzed, and experimental tests have showed that a reasonable choice of structural parameters for needle matrix can effectively control the deformation of matrix and the damage of woven fabrics during the piercing, which can provide a theoretical basis for improving the fine-weave piercing process and optimizing the woven structure.
