复合固体推进剂颗粒的三维网格自动生成

摘要

为了分析圆柱颗粒对复合固体推进剂性能的影响,必须对复合固体推进剂中三维圆柱颗粒进行网格划分.根据“力平衡”网格划分原理设计了一种适合于三维圆柱颗粒的网格自动剖分方法.编程运行结果表明,方法能自动完成划分,网格质量较高,满足要求.%For analyzing the 3D cylinder particles composing and distributing effect on composite propel-lant,it is necessary to generate mesh for the 3D cylinder particles in composite propellant. A method of mesh automatic generation is designed for the 3D cylinder particles. This method is based on force- equilibrium mesh generation theory. And distance function and mesh size function are designed for the method. The result shows that the method can automatically generate mesh and the mesh quality is good.
