The invention relates to a data processing method of an accelerated degradation test. The method comprises the following steps of obtaining service life characteristics of a medical instrument core component sample to be tested under the effect of different test stresses; establishing an acceleration model of each test stress and service life characteristics of the test stress, solving the acceleration model under each test stress, obtaining a solution acceleration model, and calculating the average service life of the medical instrument core component sample to be tested under a normal test stress according to the normal test stress and the solution acceleration model; establishing the service life distribution of the medical instrument core component sample to be tested under the normaltest stress according to the average service life of the medical instrument core component sample to be tested under the normal test stress. By means of the method, the service life distribution of the medical instrument core component sample to be tested under the normal test stress can be obtained accurately, and therefore the reliability of the accelerated degradation test is effectively improved.
Description
technical field [0001] The invention relates to the technical field of accelerated degradation tests, in particular to a data processing method for accelerated degradation tests of core components of medical equipment. Background technique [0002] Accelerated degradation test is a life test method that shortens the test period by increasing the test stress. The accelerated degradation test method provides the basis for the reliability evaluation of high reliability and long life products. There are many types of accelerated degradation tests, and the following three types are commonly used: [0003] (1) Constant stress accelerated degradation test, referred to as constant stress test, that is, first select a set of accelerated stress levels, and then divide a certain number of samples into several groups, each group is subjected to a life test at a stress level, until each group has until a certain number of samples fail. [0004] (2) The step stress accelerated degradat...
