| Other Abstract | The invention discloses a gain and direction oriented large-scale deformed paraboloid antenna panel fit rotation adjusting method. The method comprises following steps: determining the structure scheme of a paraboloid antenna and the initial position of an actuator; building a finite element model and the supporting panel nodes of the actuator; calculating the self-weight deformation of an antenna structure and extracting deformed paraboloid nodes; calculating the optimum fit paraboloid of the antenna; calculating the root-mean-square error of the deformed paraboloid and judging whether antenna gain satisfies a demand; reversing the fit paraboloid and determining a target curve under optimum working performance; determining the corresponding nodes of the deformed paraboloid and the target curve and calculating the adjusting quantity of the actuator; adjusting the position of the panel, updating the finite element model of the antenna structure, calculating the electric performance of the deformed antenna by an electromechanical coupling model, judging whether the antenna direction satisfies a demand, outputting the adjusting quantity of the actuator, and obtaining the optimum panel fit rotation adjusting quantity. The method of the invention is advantaged by that the total travel of the actuator is short, the precision of the reflection surface of the antenna is clearly improved, the antenna gain is improved, and the working direction of the antenna is ensured. |
