Embodiment 1

[0058] A method for tailoring environmental test conditions based on equipment environmental profile and environmental equivalent analysis, the steps comprising:

[0059] Step 1: Determine the test environment factors according to the equipment service area.

[0060] Equipment or its components / materials must experience different application scenarios during its life cycle. Different application scenarios represent different environmental profiles, and environmental factors have different effects and destructive effects on equipment under each profile. Generally, in the outdoor state, the equipment is mainly affected by environmental factors such as high and low temperature, humidity and heat, and solar radiation. In the storage state in the warehouse, the influence of temperature (accumulated temperature) is more prominent, and the impact on solar radiation is small or even negligible.

[0061] In this step, the environmental factors or factor combination categories (referred...

Abstract

The invention provides an environment test condition cutting method and an environment test control system based on an equipment environment profile and environment equivalent analysis. The method comprises the following steps: determining test environment factors according to an equipment service area; in combination with the determined test environment factors, acquiring corresponding environment equivalents and environment equivalent levels; acquiring an environment equivalent conversion coefficient; acquiring the environment test multiple service duration of each environment profile of the equipment; the environment test control system adopts the cutting method. By adopting the scheme of the invention, after the environment test is carried out in one typical region, related test results of other regions can be quickly given, test evaluation can be quickly carried out on newly developed equipment used in a plurality of regions, and a standard test does not need to be carried out in each region like a traditional mode; an existing point-to-point test mode is changed into a point-to-surface test mode, so that the test cost and the test time are greatly saved.

Description

technical field [0001] The invention belongs to the technical field of environmental testing, and in particular relates to an environmental testing condition tailoring method based on equipment environmental profile and environmental equivalent analysis, and an environmental testing control system adopting the tailoring method. Background technique [0002] When performing environmental testing on equipment or its components / materials, the tailoring involved is the process of selecting or changing test procedures, test conditions, and test quantities in order to help ensure the specific environment the equipment is expected to encounter during its lifetime There will be no over-engineering and under-engineering, over-testing and under-testing, so that a given piece of equipment can be manufactured and tested to operate reliably under the influence of various environmental factors and magnitudes experienced throughout its life. [0003] At present, the tailoring of fast envir...
