Embodiment 1

[0103] Such as figure 1 As shown, it is a method for estimating the high response point of pyrotechnics described in Embodiment 1 of the present application. The method includes:

[0104] Step 101, setting the initial test level value of the pyrotechnic product (also referred to as the first test level value), performing response processing on the pyrotechnic product according to the initial test level value, generating initial response result data, and setting The iterative relationship between the test level value and the initial response result data is used to iteratively process the initial test level value and the initial response result data to generate an iterative test level value.

[0105] In step 101, the initial test level value of the pyrotechnic product can be set by the recorded historical data, that is, according to the customary setting value of the type of pyrotechnic product in the recorded historical data, it can also be the The guessed value of the stimula...

Embodiment 2

[0111] In the present embodiment, the estimation of the high response point of the pyrotechnic product can be regarded as consisting of two parts, the total test sample size is 30, and x i+1 =x i -a i (y i -b i ) is used as the iterative relationship between the test level value and the response result, and the random approximation of the test level value is performed, by giving the level x of the first test 1 , run the test at this level to obtain the test result y 1 , and then obtain the level x of the second trial according to the iterative relation 2 , run the test at this level to obtain the test result y 2 , and so on, by the level x of the i-th trial i and the corresponding test results y i , get the level x of the i+1th trial according to the iterative relationship i+1 , where a i and b i is a constant whose function is to make the level x of the i-th trial i The average loss of the difference from the p-response point of the pyrotechnic product is minimized...

Embodiment 3

[0141] Combine below Figures 3 to 5 As shown, the specific application of the method for estimating the high response point of pyrotechnics is described in detail:

[0142]Step 1: Set the 0.5 quantile of the sensitivity distribution of the pyrotechnic product as the initial test level value, perform response processing on the pyrotechnic product according to the initial test level value, generate initial response result data, and set the The iterative relationship between the test level value and the initial response result data x i+1 =x i -a i (y i -b i ), performing iterative processing on the initial test level value and the initial response result data through the iterative relationship to generate the iterative test level value of each test;

[0143] Step 2: When identifying the response state corresponding to the initial response result data as a response, pass an asymmetric loss function on the iterative test level value: Perform loss weight adjustment to adjust...

Abstract

The invention discloses a method and a system for estimating initiating explosive device high-response points. According to the method, an initiating explosive device initial test level value is set, the response processing is carried out on initiating explosive devices, initial response result data is generated, the iteration relationship between the test level value and the response result is set, and the iteration processing is carried out for generating the iteration test level value; when the identification result shows that the response state corresponding to the initial response result data is response, the loss weight is increased, the iteration test level value is regulated, the processing response is carried out again, when no response is monitored, the loss weight is decreased, the iteration test level value is regulated for realizing the processing response until the response occurs, the weight loss is increased again, in addition, the response processing is carried out until the preset sample quantity is traversed, and finally, the test level value obtained through iteration is used as the estimation value of the initiating explosive device high-response points to be output. The method and the system solve the problems that in the estimation test method of the initiating explosive device high-response points, the estimation precision is poor, the invalid test occurrence rate is higher, and the estimation precision is seriously reduced due too the initial value setting deviation.

Description

technical field [0001] The present application relates to the field of sensitivity testing and analysis of pyrotechnic devices, and more specifically, relates to a method and system for estimating high response points of pyrotechnic devices. Background technique [0002] In the prior art, pyrotechnics are equipped with a small amount of medicament inside, which can be excited by small external stimuli (such as electrical stimuli such as current and voltage; physical stimuli such as falling weights) to produce combustion or explosion, thereby completing Disposable devices and devices with functions such as ignition, transmission, detonation, detonation transmission and work. [0003] For any pyrotechnic product, there is an inherent critical stimulus amount. Different pyrotechnic devices may not necessarily have the same critical stimulation amount. Under the critical stimulation amount, the pyrotechnic device may not be activated (that is, the excitation of the pyrotechnic ...
