| Abstract | 本发明公开了一种65米大型反射面天线的机电集成设计方法，主要解决大型天线设计中机电集成的问题。其步骤是：基于天线结构有限元分析，得到反射面变形后节点位移信息；根据节点理论设计坐标和变形后坐标空间位置关系，计算三角形单元质心点的理论坐标和位移；计算反射面三角形单元质心点的光程差及其对应口径面上的相位误差；将单元投影到口径面上，计算远区电场分布，得到电性能参数；以天线结构参数为设计变量，天线电性能参数最优为目标，建立优化模型；采用序列二次规划法求解优化模型，得到最优机械电磁综合设计方案，实现反射面天线机电集成设计。本发明可用于指导大型反射面天线的结构设计及对不同工况下的天线机电综合性能分析与评价。 |
| Other Abstract | The invention discloses an electromechanical integration design method of a 65m-aperture large-size reflector antenna, mainly aiming at solving the problem in electromechanical integration in large-size antenna design. The electromechanical integration design method comprises the following steps of: obtaining node displacement information after a reflector is distorted on the basis of finite element analysis of an antenna structure; designing a relation between coordinates and coordinate spatial positions after the reflector is distorted according to a node theory, and calculating theoretical coordinates and displacement of centroid points of triangular units; calculating optical path difference of the centroid points of the triangular units and phase errors on the corresponding aperture; projecting the units onto the aperture and calculating far-zone electric field distribution to obtain electrical performance parameters; building an optimization model by taking the structural parameters of the antenna as design variables and optimization of the electrical performance parameter of the antenna as a target; and solving the optimization model by adopting a sequential quadratic programming method to obtain an optimum mechanical electromagnetic comprehensive design scheme, so as to realize the electromechanical integration design of the reflector antenna. The electromechanical integration design method can be used for guiding the structural design of the large-size reflector antenna, and the analysis and the evaluation of the electromechanical comprehensive performance of the antenna under different working conditions. |
