摘　　要：研究了雷达平台的优化方法,通过尺寸优化、形状优化分析获得平台的结构形式;分析了平台梁截面尺寸对平台抗弯强度和抗扭强度的影响,采用达尔斐法将平台抗弯强度和抗扭强度的多目标优化问题统一到一个目标函数中,并通过MATLAB仿真平台对雷达平台进行多约束的尺寸优化,获得最优的平台结构尺寸,并建立平台的有限元模型对其优化结果进行仿真,验证优化结果的正确性。An optimization method for platform framework of radar is studied. The type of platform framework is obtained by dimension and shape optimization. Effects of section of framework girder on bending strength and torsion strength are analyzed. The bending strength and torsion strength of platform framework are normalized via method of Dahl Felix, and then optimization is just for one function. The dimension optimization in multi-restric- tions of platform framework is obtained via MATLAB. The finite element model of platform framework is estab- lished and the correctness of optimization result is verified by simulation.
