Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0031] like figure 1 As shown, the flexible solar cell array is generally composed of a flexible solar cell panel array composed of flexible solar cell panels 5 , an upper fixed box plate 2 , a lower fixed box plate 8 , a tensioning mechanism 1 and a guiding mechanism 9 . The upper fixed box plate 2 and the lower fixed box plate 8 are respectively located at the moving end and the fixed end of the flexible solar panel array formed by the flexible solar panel 5 . The guide mechanism 9 guides the wire rope 6 to pass through the hinges between the 5 flexible solar panels and connects with the upper fixed box plate 2, so that the flexible solar panel array formed by the flexible solar panels 5 can be unfolded and retracted in an orderly manner. The tensioning mechanism 1 tensions the steel wire rope 3 to tension the flexible solar panel array composed of the fle...

The invention relates to a method for connecting a flexible solar panel array and a rigid fixed box plate. Using this method can enable the flexible solar cell array to be connected to the rigid fixed box plate under load and high and low temperature alternating environment in space, and maintain a relatively uniform tension all the time to ensure the rigidity of the solar cell wing , The base frequency meets the requirements for use. The method includes the connection of the flexible solar panel array and the upper fixed box plate and the lower fixed box plate, the tensioning mechanism, the layout method of the tensioned steel wire rope, the connection method of the tensioned steel wire rope and the upper load-sharing beam assembly, the upper and lower load-sharing beam components The spring stiffness method, the spring layout method of the beam assembly with the upper uniform load, the uniform load transfer method of the flexible belt, and the connection method of the flexible belt and the solar panel array.
Description
technical field [0001] The invention relates to the technical field of spacecraft solar wings, in particular to a method for connecting a flexible solar array plate array and a rigid fixed box plate. Background technique [0002] The solar panel substrates of large flexible solar wings are usually composed of non-metallic materials such as polyimide and adhesives, and the length of the flexible solar panel array formed is relatively long. In the high and low temperature environment of space, the flexible solar panel array is thermally deformed due to high and low temperature. Therefore, it is necessary to form a connection method between the flexible solar panel array and the rigid fixed box panels on both sides, so that the flexible solar panel array has sufficient rigidity in orbit to meet the spacecraft attitude orbit control requirements. [0003] Large-scale flexible solar wing technology is a relatively cutting-edge space technology. At present, there is no research a...
