基于产品设计理论的飞航弹概念设计及综合优化

Cruise Missile Conceptual Design and Multidisciplinary Optimization Base on Product Design Theory

在飞航导弹气动/隐身一体化设计中,运用产品设计领域中的公理设计理论描述设计过程,两大设计公理作为设计决策的理论依据,在由功能向设计参数映射的过程中发现设计耦合,并运用TRIZ理论对产生耦合的物理矛盾与技术矛盾进行消除。由此建立的分阶段设计流程有利于在设计方案的多学科优化中运用分级优化策略,降解复杂设计任务。

In the organic design of aerodynamic and stealthy performance of the cruise missile, by using axiomatic design theory in production to describe design process, two design axioms were used as design decision basis. The axiomatic design theory helps to discover the couple design, when TRIZ theory was used to eliminate physical and technical contradictions. The design process built with the help of design theories was beneficial to the application of multilevel optimization strategy in multidisciplinary optimization, and reduce the complexity of design task.
