摘　　要：本文根据不规则对象轮廓的曲率变化以及局部形心位置,提出一套建立三维模型的数学方法,为设计与分析该对象奠定良好的基础。本文已将此方法应用于医学领域的临床工程上,成功地进行了人体中最复杂的硬组织之一,全牙列下颌骨的三维实体造型与力学分析,同时也为在其他领域形状复杂对象的设计与分析提供了一条思路。In this study,according to the changes of curvature of the outline and the partial shape center location of the irregular object,a mathematical method is set up to build up the3D model of the irregular object,which is a solid foundation to analyze and design the object.This method,which has successfully built up mandible3D model,one of the most complex parts of the body,and made mechanics analysis,has been applied in the clinical engineering and also gives some idea to analyze and design complex parts in other fields.
