摘要/Abstract

摘要： 提出一种复合材料机载天线罩多学科优化策略。以满足天线罩透波率为要求,基于等效传输线理论,对天线罩电性能进行分析,找出符合电性能指标的铺层厚度区间,将对透波率的约束转换到设计变量铺层厚度中。在满足透波率要求的前提下,建立了以质量最小为目标,结构刚度强度为约束,罩壁不同方向铺层厚度为设计变量的优化数学模型,以实现天线罩的轻量化设计。以某A-夹层机载天线罩为例进行了优化分析,研究结果表明,优化后的天线罩有显著的轻量化效果和较高的透波率表现,验证了优化方法的可行性。

Abstract: A multi-objective optimization strategy for composite airborne radome is proposed. In order to meet the requirements of the radome's transmission coefficient, based on the transmission line theory, the radome electrical performance is analyzed to find the layer thickness interval that meets the electrical performance, and the transmission coefficient constraint is converted to the design variable layer thickness. Under the condition of satisfying the electrical performance of the radome, an optimized mathematical model with the minimum mass as the target, the structural stiffness strength as the constraint and the different thickness of the cover wall as the design variables is established to realize the lightweight design of the radome. The optimization analysis is carried out with an A-sandwich airborne radome as an example. The results show that the optimized radome has significant lightweight effect and high transmission coefficient performance, which proves the feasibility of the method.
