[0008] (2) Effect of pressure difference
[0009] The effect of differential pressure is usually in the range of 1×10- 2 Pa~1×10- 5 Occurs in the vacuum range of Pa. When there is a sealed structure in the spacecraft, the internal and external differences of the sealed structure will increase, resulting in structural deformation or damage
[0010] (3) Effect of vacuum outlet
Released gases can re-condense on colder components, contaminating optics, sensors, and thermal control coatings with optically s

Embodiment 1

[0078] Such as Figure 1-6 As shown, a kind of expandable experimental box includes a box body 1, the box body 1 has a first cavity for accommodating the first sample tray 3, the upper side wall of the box body 1 is provided with an opening, and the first sample tray 3 can be Extend or retract the first cavity from the opening; both sides of the first sample tray 3 are used to install exposed material samples.

[0079] After the first sample tray 3 protrudes from the opening, it drives the exposed material samples on it to be exposed, and the exposure experiment is carried out; The side space does not occupy the peripheral space of the test box, and the space can be effectively used, and exposed material samples can be installed on both sides of the first sample tray, so that the test box can carry more samples. Optimized utilization of space.

[0080] Such as Figure 1-6 As shown, a kind of expandable experimental box also includes a transmission shaft 51 and an expansion ...

Embodiment 2

[0110] Such as Figure 1-6 As shown, a device for exposing materials outside the cabin includes an on-rail mounting bracket 7 and the above-mentioned expandable experiment box, and the box body 1 is detachably connected to the on-rail mounting bracket 7 .

[0111] In a specific embodiment, the second box is detachably connected to the on-rail mounting bracket 7, the first box is located on the outside of the on-rail mounting bracket 7, and the vertical side wall of the first box is provided with bumpers, There is a bead hitting groove on the rail mounting bracket, and when the first box is rotated to a fully preset position, the bead hitting and the bead bead groove are fit and engaged, and the opened first box is locked and positioned.

[0112] The beneficial effects of this embodiment are: this embodiment has all the beneficial effects of the above-mentioned expandable experiment box.

Abstract

The invention relates to a deployable experiment box and material outboard exposure device. The device comprises a box body, the box body is provided with a first cavity for accommodating a first sample tray, the upper side wall of the box body is provided with an opening, the first sample tray can extend out of or retract into the first cavity from the opening; and two sides of the first sample tray are used for mounting exposed material samples. After the first sample tray extends out of the opening, the exposed material sample on the first sample tray is driven to be exposed, an exposure experiment is performed; the first sample tray extends out of the opening in the upper side of the box body, the upper side space of the box body is not occupied, the peripheral space of the experimentbox is not occupied, the space is effectively utilized; exposed material samples can be installed on two sides of the first sample tray, so that the experiment box bears more samples, and the utilization rate is optimized on the limited platform space.

Description

technical field [0001] The invention relates to the field of space material exposure experiments, in particular to an expandable experiment box and a material outboard exposure device. Background technique [0002] In aerospace research, the development of space technology and space science is inseparable from the use of various materials, especially new materials. The research on the service behavior of materials in space is a space environment exposure experiment carried out for all materials serving in space environment and the parts, devices, components, components and equipment made of them. causative behavior. [0003] 1. Influence of space environment on mechanism reliability [0004] Compared with the institutions working on the ground, the working difference of space institutions is mainly caused by the space environment, and the space dynamic environment is different from the ground environment. [0005] 1.1 Influence of space environment [0006] (1) Micrograv...
