Problems solved by technology

[0003] At present, the offset parabolic antennas in the prior art are not trimmed for static balance on the ground. Since there is no static balance trim, the offset parabolic antennas will inevitably generate centripetal force when scanning in orbit, which will cause interference to satellites and cause satellite attitudes. Stable, resulting in technical problems such as antenna pointing deviation

Abstract

The invention relates to a static equilibrium balancing method for a mechanical technique, and discloses a static equilibrium balancing method for an offset fed paraboloidal antenna. The static equilibrium balancing method comprises the following steps: 1) fixing a fixture special for an antenna to a center-of-mass tester; 2) fixing the offset fed paraboloidal antenna to the fixture special for the antenna; and 3) testing the center-of-mass position of the offset fed paraboloidal antenna by using the center-of-mass tester, and balancing at a balancing position of the antenna until the center-of-mass position of the antenna is in the axis of a locating shaft. The static equilibrium balancing method solves the problem of static equilibrium balancing of the offset fed paraboloidal antenna, and has the advantages of simple implementation, high practicability and the like.

Description

technical field [0001] The invention relates to static balance trimming of mechanical technology, specifically, a method for static balance trimming of a bias-fed parabolic antenna. Background technique [0002] In order to solve the influence of the on-orbit scanning motion of the offset parabolic antenna on the attitude of the satellite, it must be trimmed statically on the ground. [0003] At present, the offset parabolic antennas in the prior art are not trimmed for static balance on the ground. Since there is no static balance trim, the offset parabolic antennas will inevitably generate centripetal force when scanning in orbit, which will cause interference to satellites and cause satellite attitudes. Stable, resulting in technical problems such as antenna pointing deviation. [0004] Do not find descriptions and reports of methods similar to the present invention. Contents of the invention [0005] In order to solve the problem of static balance trimming of an offs...
