Abstract

Firstly, this paper establishes a single objective optimization model with the goal of minimizing the area of parabola and arc in the lighting area. The parameters are traversed and solved within a reasonable range to obtain the equation of paraboloid. Then, using the method of coordinate system transformation, a single objective optimization model is established to minimize the distance from the adjusted main cable node to the ideal paraboloid. The shortest radial distance from the adjusted main cable node to the ideal paraboloid is taken as the objective function, and the expansion amount of the actuator and the position of the adjusted main cable node are taken as the decision variables to traverse each main cable node. Finally, the obtained ideal paraboloid, its vertex coordinates and the final position of the main cable node are inversely transformed by the above coordinate transformation to obtain the equation of the ideal paraboloid when the azimuth of the celestial body is 36.795 ° and the elevation is 78.169°, and the vertex coordinates are (- 49.3841, - 36.9373, - 294.4002).
