A system and method for balancing the frictional force of a solar cell array hanging and deploying device

Abstract

The invention discloses a system and method for balancing the friction force of a solar cell array suspension unfolding device. The system comprises a truss structure, a guide rail structure and a suspension structure. The truss structure comprises a truss main body, four truss supporting legs and a fixed pulley installation frame. The four truss supporting legs are symmetrically distributed in a pairwise mode and support the truss main body. The fixed pulley installation frame is arranged above one end of the truss main body. The guide rail structure is arranged below the truss main body and comprises two parallelly-arranged long guide rails and a short guide rail. The short guide rail is connected to the two long guide rails through two large tackles in a sleeving mode. The suspension structure comprises a suspension assembly, a first counterweight block, a traction rope, an upper fixed pulley, a lower fixed pulley and a second counterweight block. The suspension assembly is slidably connected with the short guide rail through a small tackle. The first counterweight block is suspended below the suspension assembly, and the weight of the first counterweight block is equal to that of a single cell panel. One end of the traction rope is fixedly connected with the small tackle, and the other end of the traction rope is fixedly connected with the second counterweight block through the lower fixed pulley arranged at the lower end of the fixed pulley installation frame and the upper fixed pulley arranged at the upper end of the fixed pulley installation frame in sequence.

Description

technical field [0001] The invention relates to the technical field of solar cell array hanging and deploying devices, in particular to a system and method for balancing the frictional force of a solar cell array hanging and deploying device. Background technique [0002] After the spacecraft is launched into orbit, the star sends detonation instructions to the pyrotechnics, and the pyrotechnics detonate after being energized, cutting off the compression rods that press the battery array on the spacecraft. It will automatically unfold on the ground and keep oriented toward the sun to ensure the normal power supply of the spacecraft. In order to ensure the reliability and safety of the solar cell array deployment in space, and to avoid the adverse effects on the solar cell array deployment process due to potential defects in product design and process, after the solar cell array products are assembled and integrated on the ground, they are generally lifted by a mechanical hoi...

AI Technical Summary

Problems solved by technology

Due to the effect of ground gravity on the product and the hanging device, the friction force Fx between the large block and the long guide rail, and the friction force Fy between the small block and the short guide rail will hinder the deployment of the battery array. In the weightless environment of space, there is no friction damping, so As a result, the ground simulation test is inconsistent with the actual space weightless environment, and the ground simulation test takes longer than the space weightless environment

[0004] The present invention proposes a method that can simultaneously balance the frictional damping in the x-direction and y-direction, which is used to simulate the space deployment test on the ground of the auxiliary battery array. At present, no description or report similar to the technology of the present invention has been found, and no similar domestic and foreign researches have been collected. material
