基于MBSE的鱼雷全电子安全系统安全性与任务可靠性分析

摘要:

随着武器装备研究的深入推进，传统方法难以满足复杂系统安全性与可靠性分析的需求。为提升系统研发与评估效率，以形式化的系统建模语言分析鱼雷全电子安全系统的安全性、可靠性成为必然趋势。本文在传统安全性与可靠性分析的基础上，基于系统工程开展安全系统建模过程，以功能需求、系统架构、活动视图以及时序逻辑控制作为安全性与作用可靠性分析的构成元素，对系统功能模型进行故障传播建模；最后以安全建模语言构建事故树模型得出安全性与可靠性的影响因素，为引信系统的安全性与可靠性分析工作提供一定参考价值。

Abstract:

With the deepening of research on embedded systems in weapons and equipment, traditional methods are difficult to meet the analysis needs of complex systems. In order to improve the efficiency of system R D and evaluation, it is an inevitable trend to analyze the safety and reliability of torpedo ESA with formal Systems modeling language. Based on the traditional reliability analysis of the security system structure, this paper carries out the corresponding system model modeling process based on SysML, and takes Functional requirement, system architecture, activity view and temporal logic control as the constituent elements of the security and action reliability analysis to model the fault propagation of the system functional model; Finally, the Tree model of accident is constructed with the safety Modeling language to obtain the influencing factors of reliability, and the safety and reliability analysis based on system engineering is realized.
