| Abstract | 本发明公开了一种基于机电耦合的大型赋形双反射面天线的副面补偿方法，包括：(1)建立天线有限元模型；(2)得到天线赋形主反射面的分段拟合面；(3)根据加载的温度载荷，计算天线主反射面变形后的节点坐标；(4)计算天线变形后的电性能；(5)得到变形后天线主反射面的最佳吻合面；(6)在最佳吻合面对应的焦轴上取焦点，通过计算天线电性能，将最佳时对应的焦点位置作为最佳馈源位置；(7)计算用于补偿天线电性能的副反射面位置调整量，计算天线补偿后的电性能；(8)判断副面位置调整前后的电性能提高量是否满足要求，调整至满足要求。本发明简化了反射面天线定量分析和建模过程，提高了计算过程，减少了天线自身重量和制造成本。 |
| Other Abstract | The invention discloses an auxiliary face compensation method for a large beam-forming double-reflection-face antenna based on electromechanical coupling. The method includes the steps that firstly, an antenna finite element model is established; secondly, a piecewise fitting face of an antenna beam-forming main reflection face is acquired; thirdly, according to loaded temperature loads, node coordinates of the deformed antenna main reflection face are calculated; fourthly, the electrical property of the deformed antenna is calculated; fifthly, the optical matching face of the deformed antenna main reflection face is acquired; sixthly, a focal point is taken from a focal axis corresponding to the optimal matching face, and the position of the focal point corresponding to the optical matching face serves as an optimal feed source position by calculating the electrical property of the antenna; seventhly, the auxiliary reflection face position adjusting amount for compensating for the electrical property of the antenna is calculated, and the electrical property of the antenna after compensation is calculated; eighthly, whether the increase amount before and after the auxiliary face position is adjusted meets requirements or not is judged, and the auxiliary face position is adjusted till the requirements are met. The reflection face antenna quantitative analysis and modeling processes are simplified, the calculation process is improved, and the weight and the manufacturing cost of the antenna are reduced. |
