摘要

针对复合快速成形中支撑生成的需求

提出了一种基于支撑线的支撑生成算法.该算法首先求出待支撑形状下表面轮廓线中被其他表面支撑的支撑线;然后利用该支撑线识别出悬臂

顶篷

孤岛等不同类型的待支撑形状

并考虑待支撑形状的几何特性和材料强度确定出需要添加支撑的区域和支撑数量

采用Paraso lid建模核心生成支撑实体并完成了上述算法的系统实现.应用实例表明

该算法能够准确地找出各类待支撑形状并能自动生成适量的支撑.

Abstract

A new algorithm for support generation based on supported line was proposed to meet the demand of support generation in hybrid rapid prototyping.It was to find out the supported line

supported by the other surface

from contour lines of the downward surface of the shapes needed support.The shapes to be supported such as overhang

ceiling and island were recognized using the supported line.The area to be added support

together with the number of support

were calculated by considering material stiffness and the geometry characteristic of the shapes needed support.Parasolid modeling kernel was used for the algorithm implementation as well as solid support structure generation.The case study indicates that the algorithm can extract the shapes to be supported exactly and genearte the proper number of support for them.
