摘要: 运用力学知识对皮影运动进行分析, 目的是模拟真实的皮影运动. 主要研究方法: (1) 根据皮 影的几何造型特征, 建立了皮影的多刚体动力学模型; (2) 根据动力学模型, 建立皮影中各部 分运动的动力学方程, 并给出其数值求解格式; (3) 根据动力学方程的离散格式, 运用FLASH 中的脚本语言编写皮影运动的程序. 并能用这个程序模拟真实的皮影动画.

Abstract: Shadow play is studied with our professional dynamics in order to find out a new method for simulating the real shadow play motion. The content of this work is as follows. First, found a dynamics model of several rigid, which respect to the geometric of shadow. Second, found dynamics equation for generating motion of every part of a shadow and make value with numerical value method. Third, generate shadow play animations by FLASH action-scrip. In a short, action-scrip could generate the real shadow play animations.

Key words: shadow play, animations, dynamics model
