> 中文摘要: 在大量CAD/CAM应用类问题中,不但需要描述实体的外形,也要求表达实体的内部信息.针对这个要求,本文提出了NURBS三参数实体造型方法和形体构筑技术.本文将此方法应用于模具CAD/CAM系统中,如有限元建模中的形体三维有限元网格生成及相应的应力分析、质量特性计算等问题.
Abstract:In many application problems of CAD/CAM, people not only need to describe the exterior of solids, but also want to know the information within the solids. In the light of this situation, this paper displays the method of NURBS tri parametric solid modeling and some construction techniques. Also the paper discusses some applicational problems in CAD/CAM of dies, such as 3 D finite element mesh generating and mass properties calculation, which are based on this method.
