Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016] The invention provides a sun blanket uniform load, tension, displacement compensation mechanism, such as figure 1 As shown, it includes a constant moment spring rope receiving mechanism 2, a tensioned steel wire rope 3, an equal load beam 4, an equal load spring 5, a flexible transition blanket 6 and a piano wire hinge 7. Among them, two sets of constant-torque spring rope-retracting mechanisms 2 are installed on the flexible solar wing fixed box plate 1, one end of the tension wire rope 3 is wound on the constant-torque spring rope-retracting mechanism 2, and the other end is vertically fixed to the load-sharing beam 4. The equal load beam 4 is connected with the flexible transition blanket 6 through a plurality of uniform load springs 5 ​​installed thereon, such as image 3 shown. The flexible transition blanket 6 is connected with the flexible ...

Abstract

The invention discloses a solar carpet uniform loading, tensioning and displacement compensation mechanism. By applying the solar carpet uniform loading, tensioning and displacement compensating mechanism, when expansion displacement of a solar wing is generated due to spatial high-low temperature alternation, uniform and constant tensioning force can be provided, the effect that the solar wing has stable rigidity property is guaranteed, the displacement compensation dimension is large, and the interference resistance is high. The solar carpet uniform loading, tensioning and displacement compensating mechanism is composed of a constant torque spring taking-up mechanism, tensioning steel wire ropes, a uniform loading beam, uniform loading springs, a flexible transitional carpet and piano wire hinges. By changing the lengths of the tensioning steel wire ropes, the displacement, generated by shrinkage and expansion, of a flexible solar carpet is compensated, and the effect that the tensile force of the tensioning steel wire ropes is constant all the time is guaranteed. Through the uniform loading beam, the uniform loading springs and the flexible transitional carpet, the concentrated tensile force transferred from the tensioning steel wire ropes is dispersed into the in-plane acting force uniformly, and the purpose of uniform loading is achieved.

Description

technical field [0001] The invention relates to the technical field of spacecraft solar wings, in particular to a flexible solar blanket uniform load, tension and displacement compensation mechanism. Background technique [0002] The large flexible solar wing has the characteristics of large area and light weight. Due to its large area, it will produce non-negligible displacement due to thermal expansion and contraction in the high and low temperature environment of space. To prevent structural damage, a set of displacement compensation must be adopted. device. In addition, the flexible solar blanket must be in a tensioned state to maintain a certain stiffness characteristic and meet the requirements of on-orbit attitude and orbit control. At the same time, untensioned sun blankets also have risks such as hooking. Therefore, tension and displacement compensation must be performed on the solar blanket. Large-scale flexible solar wings are a relatively cutting-edge space te...
