Research on the Shape Adjustment Strategy of FAST Active Reflector Based on Physical Mathematical Methods

In this paper, the optimization model is established with the goal of minimizing the comprehensive variables of the reflective panel in the process of the deformation of the base plane being an ideal paraboloid. First, a number of optimization functions are established with five key elements as the reflection factors of the comprehensive deformation of the reflective panel. The ideal paraboloid equation is obtained by solving the weighted method. On this basis, according to the property that the distance from the point on the parabola to the focal point is equal to the quasi-plane, the radial movement of the main cable node is described to fit the ideal paraboloid. According to the idea of traversal, Matlab programming is used to solve it Winner index node coordinates and offsets.
