Abstract

The ideal paraboloid is the basis for the adjustment of fast reflection panel. Through the ideal paraboloids in different directions of celestial bodies, select the main cable nodes to participate in the adjustment, and establish the corresponding model to calculate the expansion and contraction of the actuator corresponding to the main cable nodes, so as to make the reflection panel close to the ideal paraboloid as much as possible. In this paper, two methods are used to establish the ideal paraboloid model. Model 1: Based on the geometric characteristics of parabola, the results are displayed by MATLAB software; Model 2: Based on the ideal paraboloid solved by the ideal paraboloid and the proof results, the three-dimensional coordinate equation of the ideal paraboloid in any direction of the celestial body is calculated by using the coordinate axis rotation method. At the same time, the main cable point screening model and the calculation model of the adjustment expansion of the main cable point actuator are established. The adjustment parameters of the reflection panel under the celestial orientation are obtained, and the adjusted receiving ratio is 67%; The receiving ratio of the reference sphere is 20%, and the difference between them is 3 times, which proves the effectiveness of adjusting the reflection panel close to the ideal parabola.
