摘要
航空四站气体保障装备的可靠性在不断提高,而气体保障过程中的事故仍有发生,需要一种新的方法系统地去识别新的危险因素,从而提高系统的安全性。从控制的角度结合STAMP和STPA对航空四站气体保障过程进行安全性分析。首先,介绍STAMP/STPA的工作机理;然后,对航空四站气体保障过程构建STAMP模型,采用STPA安全分析方法对航空四站气体保障过程的安全性进行分析,识别不安全控制行为,对生成的不安全控制行为进行场景分析;最后,与事故树分析法(ATA)进行分析结果的比较,从而证实了该方法的优越性。结果表明:采用STAMP模型和STPA安全分析法可以更加全面地识别出不安全控制行为及其原因,更有利于保证航空四站气体保障过程的安全。
The reliability of aviation four stations gas support equipment is increasing,but the accident in the gas support process still happens.A new method is needed to systematically identify the new risk factors and improve the safety of the system.From the control point of view combined with STAMP(systems theoretic accident modeling and process)and STPA(systems theoretic process analysis),aviation four stations gas support process safety is analyzed.Firstly,the working mechanism of STAMP/STPA is introduced.Then,the STAMP model is constructed on aviation four stations gas support process.The safety of aviation four stations gas support process is analyzed by STPA safety analysis method.The unsafe control behavior is identified,and the analysis results are compared with that from the accident tree analysis method(ATA).Thus the superiority of the method are confirmed.The results show that the STAMP model and STPA safety analysis method can be used to identify the unsafe control behavior and its cause,and it is more beneficial to ensure the safety of aviation four stations gas support process.
