With the deepening of research on weapons and equipment,traditional methods are difficult to meet the analysis needs of safety and reliability in complex systems.In order to improve the efficiency of system development and evaluation,it is an inevita-ble trend to analyze the safety and reliability of torpedo electronic safety and arming system with formal system modeling language.Based on the traditional reliability analysis of the security system structure,this paper carries out the corresponding system modeling process based on system modeling language(SysML),and takes the 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 it provides a certain reference value for the safety and reliability analysis of fuze systems.
