A self-adaptive deformation mechanism of a passive space environment spacecraft

Abstract

The invention provides a passive space environment spacecraft self-adaptive deformation mechanism which comprises hybrid composite drive boards, sunshades and hinges. Every two hybrid composite driveboards and one sun-shading board are connected through the corresponding hinges to form a self-adaptive deformation unit. The multiple self-adaptive deformation units are connected through thermal insulation connecting pieces to form the self-adaptive deformation mechanism. The temperature of the hybrid composite drive boards is increased through sunlight radiation and reduced through the sun-shading boards, so that the hybrid composite drive boards generate thermal deformation along with the change of the temperature, and the terminal deformation of the hybrid composite drive boards is used for driving the whole mechanism to generate self-adaptive deformation. The sunlight is used as energy to drive the hybrid composite drive boards, dependence of the self-adaptive deformation mechanism on energy of a spacecraft is rid, and passive design is achieved.

technical field [0001] The invention relates to a deformation mechanism, in particular to a space environment spacecraft environment passive adaptive deformation mechanism. Background technique [0002] In the spacecraft, the deformation mechanism can be used as the installation interface of the payload, which can be deformed according to the specific task requirements to increase the working area of ​​the payload. The space adaptive deformation mechanism can monitor the position, angle and other information of the mechanism in real time through various sensors, and then dynamically adapt to the deformation according to the task target without human input of deformation instructions. At present, the self-adaptive deformable structure usually adopts driving equipment to drive its deformation, and the driving equipment includes smart materials such as motors, piezoelectric actuators, and shape memory alloys.
