Gravity discharge device for ground-spreading flexible solar wing

Abstract

The invention discloses a gravity unloading device for a ground-deployed flexible solar wing. Using the present invention can be applied to the extremely small spacing when the solar panels of the flexible solar wing are folded, can realize the gravitational unloading of the flexible solar wing, and can passively follow the movement of the flexible solar wing in the deployment direction of the solar wing, effectively ensuring the accuracy of the ground test precision and accuracy. The present invention includes a first limit roller device, a column, a beam, a roller device, a cantilever, an adjuster, a second limit roller device and a sling, wherein the cantilever is vertically fixedly connected to one end of the column and forms a "Z" shape with the column ;The beam is fixedly connected to the bending part of the column, and through the three roller devices, it can effectively reduce the excessive additional force and additional moment introduced by the unloading tooling. The first limit roller device and the second limit roller device are on the contact surface with the guide rail. There is a limit chute on the top to avoid vibration and shock.

Description

Technical field [0001] The invention relates to the technical field of ground deployment of solar wings, in particular to a gravity unloading device for ground deployment of flexible solar wings. Background technique [0002] With the continuous development of aerospace technology, the application of large-scale solar wings and other deployment mechanisms has become more and more extensive. At present, the domestic ground-based solar wing test device is mainly aimed at the zero-gravity deployment of ordinary solar panels. Each solar panel is connected to a hanging device, and the tension of the hanging device is adjusted to be equal to that of the solar panel connected to it. Gravity, so as to complete the gravity unloading of the solar wing deployed on the ground. As spacecraft's demand for space and energy increases, the application of flexible solar wings has attracted more and more attention in the aerospace field. However, the thickness of the flexible solar wing is relati...

Problems solved by technology

However, the thickness of the flexible solar wing is relatively thin, and the thickness of the single plate is about 1mm, and the number of folds is large when it is folded in the effective space of the spacecraft. Under the condition of ensuring the structural strength, reduce the thickness to 1mm, and the hanging device exceeds the distance between the solar panels when the flexible solar wing is folded, so the ground deployment test of the flexible solar wing cannot be completed
