Problems solved by technology

Aiming at the problem of unfolding the curled and folded inflatable tube, the existing mainstream method is to control the inflation process of the curled and folded inflatable tube through Velcro. It is necessary to attach Velcro to the outer wall of the tube. The additional quality and space requirements are high, and it is not easy to adjust the expansion. damping force, while Velcro will not work for thin walled coil folded inflatable tubes

Abstract

The invention discloses a curled and folded gas filled tube clamping and unfolding control device and a method thereof, aiming at realizing curled clamping fixation and unfolding control of the curled and folded gas filled tube. The curled and folded gas filled tube clamping and unfolding control device comprises a plug device, a rigid baffle plate and a flexible baffle plate. According to the curled and folded gas filled tube clamping and unfolding control device and method disclosed by the invention, the frictional resistance between the flexible baffle plate and the curled and folded gas filled tube is used for constraining the unfolding process of the curled and folded gas filled tube, and thus violent vibration and sway caused by non-constrained unfolding are avoided. Gas is filled to the free end of the curled and folded gas filled tube, and the gas filled tube which expanded under pressure can be gradually enfolded along the edge of the flexible baffle against the constraint of the frictional resistance after the pressure reaches a certain level. The curled and folded gas filled tube clamping and unfolding control device is simple in structure, little in occupied space, low in requirements on gas filling pressure, adjustable in frictional resistance and especially applicable to unfolding control of the thin-wall curled and folded gas filled tube; no Velcro fastener is needed to be additionally arranged on the outer wall of the tube.

Description

Technical field: [0001] The invention relates to a clamping and unfolding control device for a curled and folded inflatable tube and a control method thereof, which are applied to the clamping and unfolding control of an inflatable tube in a space vehicle. Background technique: [0002] Since the main component of the space inflatable unfolding structure is a flexible film material, the space inflatable unfolding structure has light weight, small packaging volume, low cost and high unfolding reliability, and can meet structural requirements such as space applications. In space missions, space inflatable deployment structures are more and more widely used. The curled and folded inflatable tube is a simple and typical space inflatable unfolding structure, which can be used for spacecraft inflatable support tubes, deployable antennas and solar sails, etc. Unconstrained curled and folded inflatable tubes will produce violent swings and vibrations during the deployment process, ...
