Abstract

The invention belongs to the technical field of reliability evaluation, and provides a method, a device, equipment and a medium for evaluating the reliability of a success-failure product in case of failure aiming at the reliability evaluation problem of the success-failure product under multiple stresses, so that the reliability of the success-failure product can be evaluated under the condition of failure in the test or use process of the success-failure product. The reliability of the success and failure product is further evaluated by constructing a multi-stress nonlinear model of the success and failure product and determining the model and estimating model parameters by using test data of the success and failure product. The calculation steps are clear, and the problem that an existing success and failure type reliability evaluation method does not consider multiple stresses is solved.

Description

technical field [0001] The invention relates to the field of reliability evaluation, in particular to a reliability evaluation method, device, equipment and medium of a success-or-failure product with failure. Background technique [0002] Reliability refers to the ability of a product to complete specified functions under specified conditions and within specified time. Reliability is an inherent attribute of a product, which reflects the general quality characteristics of the product. Therefore, product reliability research is very important, and product reliability evaluation is the basic content. [0003] Make-or-break products work once and cannot be used again, such as missiles, explosives, etc. Therefore, for a make-or-break product, it is usually only necessary to document whether it works. Since whether the success or failure products can work normally is random, it is assumed that the number of success or failure products that can work normally obeys the binomial ...
