摘要：

为了尽可能减少构架式索网反射面天线各模块间的缝隙对天线电性能的不利影响，以各模块中索网边界的垂跨比为设计变量，以天线电性能和索网力学性能为设计目标，建立双目标机电集成优化数学模型.采用加权系数法，将优化模型转化为单目标问题，利用粒子群算法对优化模型进行求解.以设计某7 m口径构架式天线为例，在保证索网力学性能的基础上，实现了天线电性能的最优化，证明了该机电集成设计方法的可行性与有效性.
Abstract:

An electromechanical integrated optimization model was constructed to design modular-truss mesh reflectors in order to reduce the adverse influence of the gaps between the modules on the antenna electromagnetic performance. The boundary cable sag-to-span ratios of the modules were the design variables. The antenna electromagnetic performance and the cable net mechanical performance were the objective functions. Then the optimization model was transferred into single-objective problem by using the weighting coefficient method and solved by the particle swarm optimization algorithm. The optimization of the antenna electromagnetic performance was realized on the basis of ensuring the mechanical properties of the cable net by taking the design of a 7 m diameter modular-truss mesh reflector as an example. Results showed the feasibility and effectiveness of the proposed method.
