Problems solved by technology

[0012] (2) See Table 2 and Table 3. When the sample size is small, such as n=15, the estimated accuracy of the lifting method and the Langley method (expressed in RMSE, RMSE={E(estimate-true value) 2 } 1 / 2 ) need to be further improved;
[0017] (3) The analysis of the test data depends on the parameter model F(x)=G((x-μ)σ) of the sensitivity distribution. When the model is wrongly selected, the error of the 50% action level of the pyrotechnics obtained by using the test data is very large. In practical applications, the sensitivity distribution model of pyrotechnics is usually a normal distribution or Logistic distribution, but the exact model is unknown, which brings great risks to the estimation of the 50% action level of pyrotechnics
[0022] It can be seen that the above-mentioned existing optimization test and analysis method for estimating the 50% action level of pyrotechnics obviously still has inconvenience and defects in method and use, and needs to be further improved urgently.

Abstract

The invention discloses a method and system for optimizing estimation on initiating explosive device effect level of 50%. The method comprises the following steps: setting an initial value range of the initiating explosive device effect level of 50%, and performing response processing on an initiating explosive device according to the initial value range so as to generate response result data; performing response optimization processing on the initiating explosive device according to the response result data, and acquiring derivative information corresponding to sensitivity distribution of the initiating explosive device; performing self-adaptation optimization processing on the initiating explosive device according to the derivative information corresponding to the sensitivity distribution of the initiating explosive device and preset self-adaptation rules, and generating an estimation value about the initiating explosive device effect level of 50%. Through the adoption of the method, dependence on a model and sensitivity in initial set are reduced, validness is prevented, and meanwhile the estimation precision is improved, so that the conventional insufficient estimation is overcome.

Description

Technical field [0001] This application relates to the field of pyrotechnics sensitivity test and analysis, and more specifically, to an optimization method and system for estimating the 50% action level of pyrotechnics. Background technique [0002] In the prior art, the pyrotechnic device is equipped with a small amount of medicament inside, which can be stimulated by a small external stimulus to produce combustion or explosion, so as to complete the one-time use of the functions of ignition, fire transmission, detonation, transmission and work. Devices and devices. For any pyrotechnic device, there is an inherent critical stimulus. Different pyrotechnic products, the inherent critical stimulus is not necessarily the same. The probability distribution of the critical stimulus of the initiating device is called the sensitivity distribution of the initiating device. [0003] The 50% action level of the pyrotechnic device refers to the 0.5 quantile of the pyrotechnic product's se...
