Method for constructing temperature-humidity coupled accelerated storage test model based on string function

Abstract

The invention provides a method for constructing a temperature-humidity coupled accelerated storage test model based on a string function, the steps comprising: step 1, constructing a natural environment temperature-humidity-time test string function; step 2, constructing an accelerated storage test curve; step 2 According to the temperature-humidity-time function in step 1 and step 2, the accelerated storage test time is determined by using the coupling law function model of temperature and humidity, and the accelerated storage test is carried out according to the accelerated storage test curve and accelerated storage test time constructed. The invention can not only make the accelerated storage test and the natural storage test have a better correlation, make the accelerated storage test evaluation results basically consistent with the natural environment storage test results, but also can speed up the test process, effectively shorten the test period, and improve the test efficiency , suitable for rapid evaluation of long-term natural storage products.

Description

technical field [0001] The invention belongs to the field of environmental tests, and in particular relates to a method for constructing a temperature-humidity coupled accelerated storage test model based on string functions. Background technique [0002] In the field of environmental testing, simulating the laws of the natural environment and intensifying environmental factors are the key testing techniques for stored products. The ideal condition of this testing technique is to preserve the changing characteristics of the natural storage test environment and ensure that the accelerated test is consistent with natural storage. There is a good correlation between them, and it is necessary to speed up the test process, shorten the test cycle, and improve the test efficiency. [0003] At present, there are mainly two types of storage test methods for products stored in warehouses. One is to carry out intensive accelerated tests for artificially stipulated single standard stora...

Problems solved by technology

Although the former can obtain test results in a relatively short period of time, because it only strengthens a single constant condition test, it cannot truly and effectively simulate the comprehensive effect of various climate types of warehouse environmental factors, especially the performance of products caused by changes in temperature and humidity. Degradation can easily lead to under-testing, resulting in a large deviation between the test results and the actual results; and the latter requires a long test time for natural storage tests on site, and the test efficiency is low, especially for storage tests that take quarters or years as periods or cycles. In other words, longer test time and lower test efficiency are its fatal shortcomings
