This paper reports a numerical approach, based on a nonlinear particle spring model and a collision detection procedure, to simulate the shape of a draped cloth, or a flexible sheet, together with a simple but precise three-dimensional shape reconstruction method for real fabric applications. The latter is utilized to verify the accuracy of the proposed drape simulation model. The drapes of four types of fabric on a cylinder are simulated, and the results are compared with the reconstructed shapes of the same cloths; the results show an excellent agreement. The simulation model is further used to calculate the shapes of skirts of different materials and sizes, and the effects of fabric parameters, length, and waist size are numerically investigated. The results reveal that under the same conditions, the behaviors of different materials are affected by their properties in terms of stiffness coefficients of the springs. The silk skirt looks soft and fluttering; the outer contour curve of the skirt simulated for the polyester fabric appears relatively smoother, but the shape of the cotton skirt seems to be stiffer. The skirt made of fabric of 10% cotton and 90% polyester combines the characteristics of the polyester and cotton fabric.

本文报告了一种基于非线性粒子弹簧模型和碰撞检测程序的数值方法来模拟悬垂布料或柔性片材的形状，以及用于实际织物应用的简单但精确的三维形状重建方法. 后者用于验证所提出的悬垂仿真模型的准确性。模拟了四种织物在圆筒上的悬垂性，并将结果与​​相同织物的重构形状进行比较；结果显示出极好的一致性。进一步利用仿真模型计算不同材质和尺寸的裙子的形状，并数值研究了面料参数、长度和腰围尺寸的影响。结果表明，在相同条件下，不同材料的行为受它们在弹簧刚度系数方面的特性的影响。丝绸裙子看起来柔软飘逸；涤纶面料模拟的裙子的外轮廓曲线看起来比较平滑，但棉质裙子的形状似乎更硬朗。由10%棉和90%涤纶面料制成的裙子结合了涤棉面料的特点。
