Neutron tube service life test method and device, computer equipment and storage medium

Abstract

The invention relates to a neutron tube service life test method and a device, computer equipment and a storage medium. The method comprises the following steps: acquiring neutron yields of a to-be-measured neutron tube at a plurality of moments in a working process; performing regression modeling processing on each neutron yield to obtain a neutron tube performance degradation model; processing the nominal highest neutron yield and the nominal lowest neutron yield of the to-be-measured neutron tube based on the neutron tube performance degradation model to obtain a first equivalent damage moment corresponding to the nominal highest neutron yield and a second equivalent damage moment corresponding to the nominal lowest neutron yield; according to the neutron tube performance degradation model, the first equivalent damage moment, the second equivalent damage moment and the rated yield of the neutron tube to be measured, obtaining the equivalent life of the neutron tube to be tested, sothat the problem of full-time test in the prior art is avoided, the test time consumption of the neutron tube is shortened, the problem of input cost caused by the need of a large number of test samples in the prior art is also avoided, and the test input cost is reduced.

Description

technical field [0001] The present application relates to the technical field of device reliability testing, in particular to a neutron tube life testing method, device, computer equipment and storage medium. Background technique [0002] The neutron tube is a key core component that is widely used in the fields of oil well logging, online composition analysis, explosives and drug detection. With the development of technology in various fields, neutron tubes are also required to have high reliability and long life. How to quickly and effectively test and evaluate the life of neutron tubes has become the focus of the industry. [0003] The life test method of the traditional neutron tube is to verify the life of the product by working for a long time. The neutron tube emits neutrons when it is working, so it is necessary to shield the neutron radiation when testing the life of the neutron tube, and obtain the relevant radiation safety permit, which leads to the special natur...

AI Technical Summary

Problems solved by technology

However, the cost of neutron tube products is high, and the traditional accelerated life test method requires a large number of neutron tube test samples, which costs a lot of money and faces many difficulties in practical application.

Therefore, in the implementation process of neutron tube life testing and evaluation, the inventor found that there are at least the following problems in the traditional technology: the traditional neutron tube testing technology takes a long time to test, and the test input cost is high
