摘　　要：运动微分方程的数值求解,是实现基于物理模型的织物仿真的技术关键。全面介绍了质点-弹簧模型的织物变形仿真技术,精确构建了织物的力学模型,并对几种不同的显性数值积分方法进行了详细比较,尤其是用RK-4方法对微分方程求解大大提高了解的稳定性。在此基础上,针对质点-弹簧模型在应用中存在过度拉伸的问题,指出了传统方法处理这个问题的缺陷,构造约束变形,合理解决了“超弹性”问题。此织物变形仿真技术已经应用于实际的织物动画仿真软件中,实践证明其仿真技术具有实用性和先进性。The crucial problem in cloth simulation based on physicalmodel is how to solve the motion differential equations. The simulation technology of cloth modeling based on mass spring model is presented completely, fabric mechanics models are established precisely, and several kinds of explicit numerical integration are compared detailedly, especially, using RK-4 method greatly improve system＇s stability. In these base, aiming at the mass-spring model has the ＂super elastic＂ effect in simulation. Compared to the previous methods of dealing with this problem, super elastic problem is reasonably solved using of deformation constraint. This cloth simulation method is applied to cloth software, examples proved that this method is advanced and practical.
