固体火箭发动机药柱的有限元网格划分研究

Research on the Finite Element Meshing for the Grain of Solid Rocket Motor

讨论了混合网格划分功能在对固体火箭发动机药柱进行有限元分析中的应用，对同一推进剂药柱进行了两种不同形式的网格划分，并对计算时间进行了比较，提出了推进剂药柱网格划分应注意的一些细节方面。

The application of mixed meshing for the grain of solid rocket motor was disoussed. Two different forms of meshing were performed, and the calculation time was compared. Then some details about meshing of the propellant was set up.
