基于模型的飞机复杂功能分析方法研究

当前飞机总体设计面临功能复杂，系统交联紧密的问题。针对复杂功能离散事件多、动态性强、耦合度高、建模表述困难的特点，提出一种基于模型与数据定义相结合的分析方法，进行飞机复杂功能解耦设计。该方法通过功能逻辑模型和数据建模，实现对相关系统的架构设计，完成逻辑接口向物理接口的迭代映射，最大限度保证复杂功能的相关系统接口清晰、模块划分合理，有效的提高了系统设计和验证的效率。

Research of Model-based Aircraft Complex Function Analysis Method

At present,the overall design of aircraft is faced with the problems of increasingly complex functions and close cross-linking of systems. Aiming at the characteristics of complex functionsuch as multiple discrete events , strong dynamics,high degree of coupling and difficult modeling ex-pression , this paper proposes an analysis method based on the combination of model and data defini.tion to carry out the decoupling design of aircraft complex functions. Through functional logic modeland data modeling ,this method realizes the architecture design of related systems ,completes the iter-ative mapping from logical interface to physical interface , and ensures that the related system inter-faces of complex functions are clear and the module division is reasonable to the greatest extent,which effectively improves the efficiency of system design and verification.
