example 1

[0087] Example 1 is applicable to space capture rope net in space field

[0088] The space rope net is made of Fang III fiber, in which the frame rope is a 12-strand braided rope with a diameter of 3mm; the secondary rope is a 6-strand braided rope with a diameter of 1.5mm;

[0089] The whole net is a regular hexagon with an outer rope length of 18000mm, the center of the net is a regular hexagon with a length of 600mm, and the side length of the mesh is 600mm. The whole net is composed of 29 rings from the outside to the inside except the inner and outer ropes;

[0090] Cut 37500mm long diameter 3mm frame rope according to Figure 5 Do a single radial rope arrangement, a total of 3 groups;

[0091] Cut 3 sections of 610mm long frame rope with a diameter of 3mm as the inner ring rope to connect 3 groups of radial ropes;

[0092] Cut the 110000mm long frame rope with a diameter of 3mm as the outer ring rope and connect the 3 sets of radial ropes at the outermost layer;

Abstract

The invention discloses a space rope net and a making method thereof. The space rope net is used for capturing a space target and comprises an outer ring rope, an inner ring rope, a middle rope, a radial rope, a closing-up rope, a traction rope, a tying rope and a closing-up rope ring; the outer ring rope, the inner ring rope and the radial rope constitute a bearing frame of the space rope net; aplurality of rhombic meshes are defined between the middle rope and the outer ring rope, between the middle rope and the inner ring rope as well as between the middle rope and the radial rope to forma space rope net body together; the traction rope is arranged at the vertex of the outer ring rope to pull out the space rope net; the closing-up rope is arranged on the outer ring rope and used for closing up and locking a net opening of the rope net after the space rope net captures the space target; and the tying rope is arranged on the inner ring rope and used for drawing the space rope net after the space target is captured. The invention further correspondingly discloses a knitting mode of the space rope net. The space rope net is made through an interspersed fast knot method and a crossinterspersed method, through the reasonable and optimized methods, the number of knots of the space rope net is decreased, and the overall strength of the space rope net is improved.

Description

technical field [0001] The invention relates to a design and preparation method of a space catching rope net, which belongs to the technical field of rope nets. The space rope net is mainly applicable to the field of space technology, and is also suitable for capturing or recycling various objects in natural environments. Background technique [0002] The net is a kind of flexible structure and also a kind of sparse structure. Its main feature is that the ratio between the structure size and the material quality of the structure is relatively large, that is, it can cover a considerable space or area with very little material, so it The coverage of is a very sparse coverage. In addition, the flexible material that makes up the rope net also gives the net another characteristic, that is, it can absorb shocks. Due to the sparse and flexible characteristics, the rope net can be used to achieve some special capture applications: 1) capture difficult-to-distinguish or large numbe...
