案例调整技术在固体火箭发动机总体设计中的应用

以提高固体火箭发动机(SRM)总体设计中设计经验和设计知识的重用为目的,将基于知识工程的设计方法应用于SRM总体设计。研究了SRM总体设计案例表示方式,提出了两级层次结构的案例调整模式,并针对SRM系统特点建立了SRM总体设计的因果过程模型。在此基础上,提出了SRM总体设计的案例调整框架。最后,应用该调整技术实现了具体设计实例,通过与传统总体设计比较,设计结果一致性好,证明了该技术的有效性。

Application of case adjustment technique to system design of solid rocket motor

Aiming at improving the reusability of existing experience in SRM system design,the design method based on knowledge engineering was used for solid rocket motor system design.The representation of system design case was investigated,and a case adjustment mode with two-stage architecture was put forward.The causal model of system design was established based on characteristics of solid rocket motor,then the case adjustment framework of system design was proposed.Finally the case adjustment technique was used for design example.The results were well consistent with traditional design results,which verifies effectiveness of the technique.
