Abstract

The invention provides a method and a device for determining the cable net structure of an annular mesh reflector, belonging to the technical field of spacecraft structure design. The method comprises: in accordance with that structural parameter of the reflector, the structural parameters of the front tension net and the tension of each tension rope in the corresponding tension matrix being determined, according to the three-dimensional position coordinates of each first node, determining the XOY plane coordinates of each second node forming the rear tension net, determining the force densityof each second rope segment according to the force density of each first rope segment, and determining the three-dimensional position coordinates of each second node forming the rear tension surfaceaccording to the plane coordinates of each second node, the force density of each second rope segment, and the tension of each tension rope; according to the three-dimensional position coordinates ofthe first node and the three-dimensional position coordinates of the second node, the length of each tension rope being determined to determine the entire cable network structure. The invention effectively solves the possible problems of the post-tensioned net rope when the length of the truss vertical bar is low, and obtains a stable and reliable cable net structure which meets the electric performance requirements.

Description

technical field

[0001] The invention relates to a method and a device for determining a cable net structure of an annular mesh reflector, and belongs to the technical field of aerospace vehicle structure design. Background technique

[0002] In order to detect low-power signals, the new generation of mobile communication satellites, electronic reconnaissance satellites, and data relay satellites have put forward an urgent need for large-aperture deployable antenna reflectors. Among them, the ring-shaped truss-type deployable antenna reflector (also known as the peripheral truss-type deployable antenna) has the characteristics of simple structure, high reliability, and large expansion-retraction ratio, and the increase of the caliber within a certain range will not change the antenna reflector. The structural form, the mass will not increase proportionally, it is the most ideal structural form of the large spaceborne deployable antenna reflector at present.
