摘要/Abstract

摘要： 根据气体辅助注射成型的特点，在塑件表面三角形网格的基础上，提出了手工拟合气道路径和自动求解气道节点相结合的方法生成气道网格，并给出了求解多边形最大内切圆的气道网格算法和优化气道网格的算法，通过软件应用和实例分析，证明所提出的算法是行之有效的。该算法为气体辅助注射成型模拟分析的数值计算提供了依据。

Abstract: According the characters of parts produced by gas-assisted injection molding, an algorithm of gas-channel mesh was formulated. Combining the manual setting of gas-channel path and automatic building of gas-channel node, semiautomatic generation of gas-channel mesh was realized. The algorithm was applied in CAE system, some case studies were used to verify that the generation was correct and reliable, which is prerequisite for numerical simulation of gas-assisted injection molding process.

Key words: Surface mold, Gas-channel mesh, Gas-channel path, Gas-channel node
