A Study On Safety And Reliability Of Initiating Device System

Initiating device system is an important subsystem of weapon system. That of initiating system to a great extent impacts the safety and reliability of weapon system. Developing and enhancing safety and reliability of initiating system is one of the most important methods to prevent failures. However, to increase safety and reliability of initiating system is a systems engineering. It involves developing, designing, testing, evaluating, building disable mode and its database, using, managing of advanced technology initiating device and so on. In this paper, the methods of enhancing safety and reliability of initiating device based on assessment technology and management is researched. Among current statistic methods of assessment method, complete run-down method and Bruceton method are more common than others. In the paper, the two methods are compared through abundant data of sensitivity test. The results show that Bruceton method is more optimistic than complete run-down method when the safety and reliability of initiating device are evaluated. When the 0.999 response is evaluated, the stimulating value of Bruceton method is 20% lower than that of complete run-down method. Furthermore, the cause is analyzed and the result is modified. From the point of management, a closed loop information analysis and feedback system is advanced according to the importance of management. It is used to enhance the rationality of initiating device in designing, producing, storing, using and so on, and it is also used to decrease the personal defects and improve the safety and reliability of initiating device.
