摘要： 提出了一个基于离散平面的层次化装配模型。通过将一般CAD模型进行零件曲面离散、信息转换等操作建立离散面片模型，并给出了曲面离散化的方法。离散面片模型大大提高了装配规划中干涉检查、碰撞检测及显示等方面的效率。

Abstract: This paper presents an hierarchical assembly model based on discrete facets.This model is established through discreting the part surfaces and transforming the part information in the general CAD models.The method of surface discretization is also discussed.The proposed assembly model largely improves the efficiencies of intervention inspection and collision detection and displaying parts in the virtual assembly planning.
