ABSTRACT

This paper mainly studies how to determine an ideal paraboloid when the adjustment of "fast" is constrained. In the case of vertical illumination, the operation feasible region of the main cable node is the region between two triangular reflection panels. Because the ideal paraboloid can make the parallel electromagnetic waves gather in the feed cabin and the expansion and contraction of the actuator have a range, the problem can be transformed into a single objective optimization problem for two-dimensional graphics. Combined with the parameters, geometric knowledge, light reflection principle and accessory data of the triangular element mirror, the included angle between the triangular element mirror and the horizontal line can be calculated by MATLAB, and then the relationship between the expansion amount of the actuator and the x-axis can be deduced, and finally the ideal paraboloid can be obtained.
