摘要:

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。

Abstract:

An improved automatic approach for 3 D grain burning area design of solid rocket motor was developed. According to the input data of the design indexes and the whole variables, the approach could automatically determine a number of probable projects of grain construction, optimize the grain configuration geometry for every project, select the preferred projects, and obtain the final grain burning area design results. The approach was utilized in 3 D grain burning area design of some experimental motors.The results show that this approach is practical and effective.
