提出了一种三维药柱燃面自动化设计的新方法：根据设计者输入的设计指标和全局参数值，自动确定一系列药柱结构可选方案，自动对每一个结构方案进行药形几何参数的优化设计，自动对结构方案进行优选，并确定出可行的药柱设计方案，输出燃面设计结果。经实例设计，表明该方法是切实可行的。 A new method for the automatic design of the three-dimensional drug grain burning face is proposed. According to the design indexes and global parameter values ​​input by the designer, a series of optional formulas of the drug column structure are automatically determined, and the geometry parameters of each configuration are automatically determined Optimize the design, optimize the structural scheme automatically, and determine the feasible design scheme of the drug column, and output the design result of the combustion face. The example design shows that the method is feasible.
