Problems solved by technology

For such a complex network system, it cannot be simply equivalent to a series or parallel model, and the reliability of the system is not easy to establish and evaluate
[0004] For the reliability evaluation of this complex network system, the general processing method is to connect the reliability indicators of each terminal pyrotechnic product in series, and the reliability of the previous detonation and detonation links are all regarded as 1. This evaluation method , because the index of the previous detonation link is not considered, the evaluation result of the system reliability is too radical

Embodiment Construction

[0048] According to the characteristics of the detonation transmission sequence of the non-electrical detonation transmission system, the present invention establishes a corresponding reliability function block diagram. In the system, each detonation transmission sequence is independent of each other. Probability formula to evaluate the reliability index of complex network systems:

[0049] 1) Establish a reliability functional block diagram;

[0050] 2) The detonator unit has only two possible situations of detonation or non-detonation. In order to calculate the reliability of the non-electric detonation system, according to the total probability formula, the various possible situations of at least two independent detonation units are decomposed. ;

[0051] 3) According to the decomposition situation, the explosion transfer unit is simplified into a series or parallel model, and the reliability of each series-parallel model is calculated;

[0052] 4) Bring the calculation r...

Abstract

The invention discloses a reliability evaluation method for a non-electric explosion propagation firer system. The kind of non-electric explosion propagation system which is a complicated network system and does not belong to parallel connection or serial connection is evaluated by utilizing a thought of total probability formula, the reliability of this kind of complicated network system is evaluated according to the work reliability of different explosion propagation links, and the reliability of the non-electric explosion propagation system can be accurately calculated.

Description

technical field [0001] The invention discloses a reliability evaluation method, in particular to a reliability evaluation method of a non-electric detonation pyrotechnic system, belonging to the technical field of pyrotechnic product reliability. Background technique [0002] Whether it is widely used in the launch vehicle pyrotechnic system, the non-electric detonation pyrotechnic system is a method that converts electrical energy into detonation waves, and detonates through multiple restricted detonating cords, and then detonates each terminal pyrotechnic product. Complex network system. Compared with the detonation system of electric detonation, it has the advantages of high synchronization of terminal work, power saving, and redundancy of detonation. [0003] Reliability work is the key to the current research and development work, and the establishment of reliability models is the basis for carrying out reliability work, and its accuracy directly affects the distributi...
