Warp knitted fabrics are typically three-dimensional (3D) structures, and their design is strongly dependent on the structural simulation. Most of existing simulation methods are only capable of two-dimensional (2D) modeling, which lacks perceptual realism and cannot show design defects, making it hard for manufacturers to produce the required fabrics. The few existing methods capable of 3D structural simulation are computationally demanding and therefore can only run on powerful computers, which makes it hard to utilize online platforms (e.g. clouds, mobile devices, etc.) for simulation and design communication. To fill the gap, a novel, lightweight and agile geometric representation of warp knitting loops is proposed to establish a new framework of 3D simulation of complex warp knitted structures. Further, the new representation has great simplicity, flexibility and versatility and is used to build high-level models in representing the 3D structures of warp knitted fabrics with complex topologies. Simulations of a variety of warp knitted fabrics are presented to demonstrate the capacity and generalizability of this newly proposed methodology. It has also been used in virtual design of warp knitted fabrics in wireless mobile devices for digital manufacture and provides a functional reference model based on this simplified unit cell of warp knitted loops to simulate more realistic 3D warp knitted fabrics.

基于圈纱几何晶胞的经编组织三维仿真

经编针织物通常是三维 (3D) 结构，其设计在很大程度上依赖于结构模拟。现有的仿真方法大多只能进行二维（2D）建模，缺乏感性真实感，无法体现设计缺陷，制造商难以生产出所需的面料。现有的少数能够进行 3D 结构仿真的方法对计算要求很高，因此只能在功能强大的计算机上运行，​​这使得很难利用在线平台（例如云、移动设备等）进行仿真和设计交流。为了填补这一空白，提出了一种新颖、轻巧且灵活的经编线圈几何表示，以建立复杂经编结构的 3D 模拟新框架。更多，新的表示具有极大的简单性、灵活性和多功能性，用于构建高级模型来表示具有复杂拓扑结构的经编针织物的 3D 结构。展示了各种经编针织物的模拟，以证明这种新提出的方法的能力和普遍性。它还被用于无线移动设备中经编织物的虚拟设计以进行数字化制造，并基于这种简化的经编线圈单元提供功能参考模型，以模拟更逼真的 3D 经编织物。展示了各种经编针织物的模拟，以证明这种新提出的方法的能力和普遍性。它还被用于无线移动设备中经编织物的虚拟设计以进行数字化制造，并基于这种简化的经编线圈单元提供功能参考模型，以模拟更逼真的 3D 经编织物。展示了各种经编针织物的模拟，以证明这种新提出的方法的能力和普遍性。它还被用于无线移动设备中经编织物的虚拟设计以进行数字化制造，并基于这种简化的经编线圈单元提供功能参考模型，以模拟更逼真的 3D 经编织物。
