Abstract

A manufacturing method of a high-precision tension cable net unit of a mesh antenna comprises the following steps that firstly, a moving datum (4) on a linear displacement executing mechanism (2) is adjusted to be zero, and the distance between a fixed datum (3) and the moving datum (4) is calibrated through a theodolite test system; secondly, one end of a tension cable is manufactured to be a first fixed ring, and the fixed datum (3) is sleeved with the first fixed ring; thirdly, after the other end of the tension cable is used as a free end and folded in two, the part, folded in two, of thetension cable is sleeved with a compression connection terminal, and a moving ring is manufactured; fourthly, the moving datum (4) obtained in the first step is sleeved with the moving ring obtained in the third step, the free end of the tension cable is wound around a pretension loading device (6), and then tension is applied; fifthly, the linear displacement executing mechanism (2) is controlledto move, after the linear displacement executing mechanism (2) drives the moving datum (4) to move to a preset position, the compression connection terminal in the third step is tightly pressed, anda second fixed ring is manufactured.

Description

technical field [0001] The invention relates to a method for manufacturing a high-precision tension cable net unit of a mesh antenna, which belongs to the technical field of space-borne mesh antenna manufacturing. Background technique [0002] The surface accuracy of a satellite antenna is an important index to measure and evaluate the quality of the antenna. It not only directly affects the aperture efficiency of the antenna, determines the shortest wavelength that the antenna can work, but also affects the main lobe width and side lobe structure of the antenna pattern. For large, high-precision, flexible mesh antennas, the antenna profile is mainly maintained by the antenna flexible tension cable net, and the accuracy of the antenna profile is mainly guaranteed by the manufacturing accuracy of the flexible antenna tension cable net, and the flexible tension cable net It is spliced ​​by hundreds of tension cable net units, so the processing accuracy of the tension cable uni...
