Embodiment 1

[0068] Example 1, see figure 1 , a method for evaluating the reliability of an accelerated degradation test based on the gray system theory provided by an embodiment of the present invention includes the steps of:

[0069] 101. Perform data preprocessing on the raw data obtained from the accelerated degradation test to obtain preprocessed data;

[0070] Since the original data of the accelerated degradation test is likely to be discrete data without special rules, the preprocessing of the data in the process of analysis and reliability assessment has also become an indispensable step in the reliability assessment. After the accelerated degradation test The acquired raw data is subjected to data preprocessing to obtain preprocessed data.

[0071] 102. Using gray system theory to analyze the preprocessed data to obtain gray system theory analysis data;

[0072] In the embodiment of the present invention, in order to obtain more accurate reliability evaluation results, the gray...

Abstract

The embodiment of the invention discloses a gray system theory based accelerated degradation test reliability assessment method. The method includes the steps: (1) performing data pretreatment on original data acquired by an accelerated degradation test, and acquiring pretreated data; (2) analyzing the pretreated data through the gray system theory, and acquiring gray system theory analysis data; and (3) performing reliability assessment on the ray system theory analysis data. Compared with the prior art, the method can correctly recognize and effectively control operation behaviors of the system, and is close to engineering practice.

Description

technical field [0001] The invention relates to the technical field of accelerated degradation test evaluation, in particular to an accelerated degradation test reliability evaluation method based on gray system theory. Background technique [0002] Life test is a traditional product reliability verification method, which only records product failure and test time, but the key performance parameters of many products will change slowly during use or storage. This is called the performance degradation process. When the performance degradation exceeds a certain standard After that, the product is considered to be invalid, so the failure of the product is a cumulative process of performance degradation. Obviously, using the various parameter data generated during the complete performance degradation accumulation process to further analyze the reliability information of the product contained in the data can effectively evaluate the reliability of the product. [0003] With the c...
