摘　　要：根据文献描述,建立了纱线织物结构三维线圈模型。根据质点-弹簧模型原理,对原模型进行简化,建立三维线圈简化模型,对简化模型的相对误差进行了分析。基于简化模型设计VRML变形仿真程序,选择显式欧拉法对简化模型进行数值求解,实现对服装衣片上的某一质点施加一空间方向的力,对纱线织物结构受力变形情况进行了仿真。仿真结果真实反映了织物在受力状态下的变形情况。Three-dimensional coil model of yarn fabric structure is established based on the description of the references. The original model is simplified according to the principle of mass-spring model. Then,simplified 3D coil model is established. The relative error of the simplified model is analyzed. VRML deformation simulation program is designed based on the simplified model. Numerical values of the simplified model arefigured out with the explicit Euler method. Stress deformation of yarn fabric structure is simulated when a force in the direction of space is imposed on a mass point of the garment. The simulated results turly reflects the deformation of fabric under stress.
