摘要:

针对当前民机系统功能设计过程中缺乏形式化描述、模型复用性不强与动态模型建立不足等问题,将基于模型的系统工程(MBSE)理念引入民机系统设计过程中,提出了一套基于系统建模语言(SysML)的民机系统功能设计方法。首先定义用例模型,抽象出系统的顶层功能愿景,进而开展功能的分解分配与系统静态功能模型的构建;接着建立系统的功能流模型,然后进行功能泳道划分与功能交互序列构建,从多角度分析系统的行为特性,在此过程中结合活动图、泳道图和序列图构建系统的动态功能模型;最后给出系统的结构接口实现,形成一套逻辑性强的完备的功能设计方案。以民机航电系统为例进行功能设计,结合SysML建立航电系统的功能模型,验证了该方法的可行性与有效性,适用于民机系统的功能设计。

Abstract:

In response to the lack of formal description, weak model reusability, and insufficient establishment of dynamic models in the current civil aircraft system function design process, the concept of model-based systems engineering (MBSE) was introduced into the civil aircraft systems design process, and a set of methods for civil aircraft system function design based on the systems modeling language (SysML) was proposed. Firstly, the methods defined the use case model, abstracted the top-level functional vision of the system, and then carried out the decomposition and allocation of functions and the construction of the static function models for the system. Next, it established a function flow model of the system, and then divided the function swim lanes and constructed function interaction sequences, aiming to analyze the behavioral characteristics of the system from multiple perspectives. During this process, dynamic function models of the system were constructed by combining activity diagram, swimlane diagram, and sequence diagram. Finally, it provided the implementation of the system’s structural interface, forming a set of comprehensive function design methods with strong logic. Taking the civil aircraft avionics system as an example for function design, function models of the avionics system were established using the SysML verifying the feasibility and effectiveness of the proposed method, which was applicable to the function design of civil aircraft systems.

Key words: function model, SysML, civil aircraft, MBSE, behavioral characteristics
