Solar simulator irradiance uniformity detection device and detection method in space environment

Abstract

The invention provides a solar simulator irradiance uniformity detection device in a space environment. The detection device comprises a test stand, a cable in a tank, test units, a cable outside the tank, a measurement and control cabinet outside the tank, and a control terminal. The test stand, the test units and the cable in the tank are arranged in a vacuum tank. The test units are arranged on the test stand. The test units are connected with the cable outside the tank through the cable in the tank. The cable outside the tank is connected with the measurement and control cabinet outside the tank. The measurement and control cabinet outside the tank is connected with the control terminal. The test stand is in a cross-shaped structure. Five test units are arranged. One of five test units is located at the center of the cross-shaped test stand. The other four test units are respectively arranged at upper, lower, left and right positions one meter from the center of the cross-shaped test stand. The invention further provides a detection method of the detection device. The detection device provided by the invention has the advantages of lightweight design, simple test principle, easy operation and good stability, can be operated by a person, and can adapt to a special low-temperature vacuum environment.

Description

technical field [0001] The invention relates to the technical field of a high-intensity radiation uniformity detection device, in particular to a solar simulator radiation uniformity detection device and detection method in a space environment. Background technique [0002] In the vacuum thermal test of the spacecraft, heating sheets, lamp arrays, heating cages and solar simulators are mainly used to simulate the heat flow outside the space. In the heat balance test, it is the closest simulation method to the solar radiation. In order to ensure the accuracy of the test, it is necessary to test the irradiation uniformity of the solar simulator under vacuum and low temperature. [0003] At present, in China, the various radiation indicators of the solar simulator, including the uniformity of radiation, are only tested under normal temperature and pressure. However, due to the slight complex deformation of the solar simulator lens before and after vacuuming, and after passing...
