| 摘 要： | 基于Pro/E环境求解诸如卫星舱的复杂布局优化问题，需要对3D不规则物体频繁进行干涉量计算，干涉量快速计算已成为实现复杂布局优化的瓶颈。基于Pro/E二次开发，将原实体简化为长方体包围盒和内含基本几何形体（长方体和圆柱）组合的双层逼近模型，实体简化模型干涉量计算归结为对包围盒内含基本几何体的计算，最后可以用Pro/E精确校验。经数值实验表明，该方法对原实体模型的逼近程度和计算耗时的均衡优于包围盒方法、八叉树方法和传统的全人机交互方法。

| Abstract: | The interference calculation of irregular solid model is performed frequently when solving the complicated layout optimization problems based on Pro/E.The fast interference calculation becomes to the bottleneck of the layout optimization.Therefore,a solid model simplification approach is proposed by Pro/E secondary development.The method simplifies the solid model into bilevel model:The first level is the bounding box,while the second level is composed of regular geometry models.The experimental results sho... |
