摘要
随着民机系统综合化程度的不断提高,各系统主体之间交互关系复杂、涌现性突出。传统的安全性分析方法以线性逻辑为主,未能完全满足系统风险高效识别的要求。为此,提出一种基于改进FRAM-STPA的民机系统安全性分析方法。构建融合模型,实现民机系统图形化功能建模与耦合分析;根据建模得到的功能单元潜在变化表型和系统潜在危险控制动作,生成系统全局功能影响关系,并通过量化功能模块的可变性风险识别系统安全运行关键功能模块。以民机刹车系统为例展开分析,并使用Word2Vec挖掘维修文本信息,验证分析结果的准确性,为民机安全性分析提供理论和方法参考。
As civil aircraft systems increasingly integrate,the complex interactions among various system components and the emergence of unforeseen issues have become prominent.Traditional safety analysis methods,primarily based on linear logic,have failed to fully meet the requirements for efficient identification of system risks.Therefore,an improved FRAM-STPA approach for the safety analysis of civil aircraft systems is proposed.In order to carry out graphical functional modeling and coupling analysis of the aviation system,an integrated model must be built.Based on the modeling results,including the latent phenotypes of functional units and potential unsafe control actions within the system,it establishes the system-wide functional impact relationships and quantifies the variability risk of functional modules.In order to verify the accuracy of the analysis results,Word2Vec is used to mine maintenance text information,and the airplane braking system is used as an example to illustrate the analysis.This approach provides theoretical and methodological references for civil aircraft safety analysis.
