Reliability analyzing method of initiating explosive device testing system

Abstract

The invention provides a reliability analyzing method of an initiating explosive device testing system, and relates to the field of quality detection of initiating explosive devices in aerospace systems. The reliability analyzing method comprises the following step ofproviding a reliability evaluation method based on a dynamic bayes network for the reliability of a flexible testing system of an initiating explosive device in an aerospace system. The aerospace-stage initiating explosive device has extreme requirements forthe reliability, and the reliability has to reach 100%. The quality of theinitiating explosive device is determined by adopting an ignition test, the initiating explosive device belongs to a disposable product, only a limited sampling ignition test is performed on each batch of initiating explosive devices to evaluate the overall quality characteristics of the initiating explosive device, and a testing system is an important guarantee to accurately evaluate the qualityreliability of the initiating explosive device. Since the varieties of theaerospace initiating explosive devices are large, and initiating explosive devices of different varieties are equipped with different testing instruments and different testing channels and have different parameter configurations. The reliability of the testing system is related to time and product task batches, a dynamic bayes network structure chart of the testing system is established by using the dynamic bayes network evaluation method, the timing sequence causality relationship between different time slices is combined with the causality relationship in time slices, and dynamic analysis and prediction are performed through quantitative reasoning.

Description

[0001] The invention relates to the technical field of quality detection of aerospace pyrotechnic products, in particular to a reliability analysis method for a testing system of aerospace pyrotechnic products. Background technique [0002] Aerospace pyrotechnics are an indispensable and important part of the space flight system. The number of various types of pyrotechnics in a rocket can reach thousands, and almost every action and function of the rocket is inseparable from the batch hanger. The pyrotechnics for the whole body of the rocket. Any failure of pyrotechnics may lead to the failure of space launch missions, and even bring catastrophic consequences; aerospace pyrotechnics are explosive products and can only be used once, which makes it impossible to conduct fire tests on all products. Reflect the overall quality with a limited number of fires; due to the wide variety of aerospace pyrotechnics, there are more than 1,200 commonly used aerospace pyrotechnics, and the t...
