Abstract

The invention relates to a device for exposing materials outside the cabin, which is installed on the outer platform of an orbiting spacecraft, including a base, a load center frame, a mounting bracket, several experimental boxes, and a four-degree-of-freedom inspection robot arm. A gap is left; the load center frame is vertically fixed and installed at the center of the base; each side of the base corresponding to the mounting bracket is provided with at least one assembly port; several test boxes are detachably installed in the assembly port; four degrees of freedom inspection One end of the robotic arm is rotatably connected to the top of the load center frame, and the other end is movable in the gap; an image acquisition device is slidably installed on the four-degree-of-freedom inspection robotic arm; where the other end of the four-degree-of-freedom inspection robotic arm moves out of the gap , the test box is opened, and the exposed surface of the test box is perpendicular to the base and parallel to the side of the corresponding base; the four-degree-of-freedom inspection robot arm drives the image acquisition device to rotate around the load center frame, and sequentially inspects the exposed surfaces of several test boxes. check.

Description

technical field [0001] The invention relates to the field related to the external exposure of space station materials, in particular to a material external exposure device. Background technique [0002] In order to meet the needs of future deep space exploration, it is of far-reaching significance to study the in-orbit service behavior of materials in the field of basic disciplines, and to study the in-orbit characteristics and changes of materials. During the missions of the former Soviet space station and the International Space Station, on-orbit exposure tests of metal and non-metal materials have been verified many times, and significant scientific research results have been achieved. However, my country is still in its infancy in terms of space material exposure. In order to meet the task requirements of material space exposure, it is urgent to involve a test system that can be repeatedly installed, repeatedly locked and released on the track, and automatically unfolded...
