Embodiment 1

[0060] use figure 1 The test device of the shown embodiment performs the atomic oxygen / near ultraviolet / far ultraviolet / temperature cycle / vacuum comprehensive irradiation synergistic test on a modified polyimide film material. Specifically, in this embodiment, for the film sample, the fixture is such as figure 2 and image 3 shown, divided into figure 2 bottom plate shown and as image 3 There are two parts of the cover plate shown, and the protrusions on the bottom plate correspond to the grooves on the cover plate. The thin film sample was placed in the irradiation area enclosed by the protrusion of the base plate, the cover plate and base plate were fixed, and the sample holder was fixed above the temperature cycling simulator.

[0061] The specific test steps are as follows:

[0062] Step 1. Before the test, calibrate the intensity and uniformity of ultraviolet radiation, and the density and uniformity of atomic oxygen beams;

[0063] Step 2. Place the sample to be...

Abstract

The invention provides a space environment multi-factor collaborative test device. The space environment multi-factor collaborative test device comprises a space environment simulation system (1), a vacuum irradiation chamber (2), an ultraviolet irradiation intensity measurement system (3) and a control system (4). The invention further provides a testing method of the space environment multi-factor collaborative testing device. The space environment multi-factor collaborative test device is high in integration level, can carry out comprehensive irradiation collaborative tests of five space factors of atomic oxygen irradiation / near ultraviolet irradiation / far ultraviolet irradiation / temperature circulation / vacuum environment at most, and has good flexibility; the atomic oxygen beam density and uniformity, the near ultraviolet radiation intensity and uniformity, the temperature cycle temperature and the vacuum degree of a vacuum simulation system in the comprehensive irradiation test can be measured, and the accuracy of comprehensive irradiation test data is guaranteed.

Description

technical field [0001] The invention belongs to the field of material science research, relates to the field of space material science and technology, and more particularly relates to a space environment multi-factor collaborative test device and a test method. Background technique [0002] The space environment faced by spacecraft during the operation of low earth orbit mainly includes atomic oxygen, solar electromagnetic wave irradiation, vacuum, temperature cycle and so on. Among them, atomic oxygen is oxidative, which will cause changes in the physical properties of materials such as optics, mechanics and thermals, and its harm to materials is far more serious than other environmental factors. There is a synergistic effect between various factors. For example, the temperature cycle will cause defects such as cracks on the surface of the material, which provide a channel for atomic oxygen to enter the material, aggravate the oxidation and erosion of the material by atomic...
