摘　　要：介绍了一种毛衫织物动态仿真的方法.通过对影响织物动态仿真因素的综合分析,以毛衫织物为例,结合毛衫织物柔软、弹性好的特点,建立质点弹簧模型;利用二分法求解碰撞检测来降低运算的复杂度,以提高仿真速度;结合毛衫织物与球体碰撞时短暂"静止"的现象,以差别化求解碰撞响应方法计算质点受力、速度,从而实现了毛衫织物的仿真.实践表明采用该方法对毛衫织物进行动态仿真,效果比较逼真.A dynamic simulation way on wool fabric is introduced. Through a comprehensive analysis of factors affecting the dynamic simulation of the fabric, using wool fabric as a example, combining with it＇s good soft and elasticity, a mass-spring model is set up, and the dichotomy is used to solve the collision detection and improve simulation speed; combining with the phenomenon of ＂insant quiescency＂ when the fabric is colliding a sphere, a differentiation way is created to solve the mass＇s force and speed during the collision response. The results show that this method has a better result for the dynamic simulation of wool fabric.
