Embodiment 1

[0020] Embodiment 1: as Figure 1 to Figure 3 As shown, a multi-factor comprehensive plateau alpine climate environment simulation accelerated test device, the device includes a test box, an air pressure system, a light source system, a temperature and humidity adjustment system, a circulating air system and a control system. The test box is an inner pressure-bearing container, and the top of the container is composed of a high-transparency and high-strength glass plate 10 and a metal pressure-bearing net, and the high-transparency and high-strength glass plate is installed above the metal pressure-bearing net. An automatic drain valve 24 is installed at the bottom of the test box, through the automatic opening and closing of the upper solenoid valve 25 and the lower solenoid valve 27, the liquid accumulation formed during the test process is automatically removed through the drain pipe 26.

[0021] Described pneumatic system is made up of vacuum pump 23, solenoid valve and co...

Embodiment 2

[0026] Embodiment 2: The difference from Embodiment 1 is that the light source 9 is a combination of a metal halide lamp and an ultraviolet fluorescent lamp. Each lamp in the light source 9 can be turned on individually or simultaneously, and the power of each lamp can be adjusted within a certain range. The metal halide lamp in the light source 9 is installed on the top of the test chamber, above the high-transparency glass; the ultraviolet fluorescent lamp 29 is installed under the high-transparency glass, and is protected by a quartz tube to ensure that the ultraviolet fluorescent lamp can work normally under the harsh environmental conditions in the chamber. Work. Combination and power are controlled by PLC, single chip microcomputer or PC program.

[0027] By controlling some environmental factors, the present invention can also simulate cold area environment, hot and dry environment, tropical rainforest environment and aerial environment, etc.; this device can be used t...

Abstract

The invention discloses a multi-factor comprehensive plateau alpine climate environment simulation acceleration test device, which comprises a test box body, a pressure system, a light source system,a temperature and humidity adjustment system, a circulating wind system and a control system. The test device uses a PLC or a single-chip microcomputer to control radiant power and total ultraviolet ratio of a light source as well as actions of pressure rise and fall, temperature rise and fall, humidification and dehumidification and wind speed and the like. The test device can form an artificially-simulated or enhanced plateau alpine environment composed of five environmental factors, that is, light, air pressure, temperature, humidity and wind speed, and is used for testing and evaluating plateau alpine climate environment adaptability of materials, parts and equipment. By controlling some environmental factors, the test device can also simulate cold environment, dry and hot environment,tropical rainforest environment and high-altitude environment and the like. The device can also be used to carry out a number of existing standard tests, comprising low pressure test, light aging test, high and low temperature test and damp heat test and the like to achieve an effect of one box with multiple uses.

Description

technical field [0001] The invention relates to a simulated accelerated test device, in particular to a simulated accelerated test device for a multi-factor comprehensive plateau alpine climate environment. Background technique [0002] Under the influence of plateau alpine climate environment, the equipment will have problems such as malfunction, deformation of the sealed shell, welding cracking, structural damage, equipment leakage, abnormal engine start and combustion, and power drop; polymer materials are easy to age, and the protective coating on the surface of the vehicle and The service life of sealing materials in Tibet is only about one-third of that in the Mainland, and the service life of some packaging materials is only one-tenth of that in the Mainland. Existing test techniques for simulating plateau environments mainly include low-pressure tests and high-low temperature and low-pressure test techniques, which do not incorporate factors such as solar radiation, ...
