摘要： 高速飞行器蜂窝夹芯吸波/透波天线罩结构在服役时面临着严酷的力热载荷，而目前的研究缺乏对吸波/透波结构在高温承载环境下力热电性能的匹配设计研究。为保证结构在高温承载环境下具备稳定和优良的力热电性能，提出一种面向蜂窝夹芯吸波/透波结构的力热电性能匹配设计方法。首先，分析力/热载荷对蜂窝夹芯吸波/透波结构电性能的影响，建立蜂窝夹芯吸波/透波结构的力热电耦合分析模型，构建面向力热电匹配设计的优化设计模型。然后，设计一种具备宽带低吸高透功能的蜂窝夹芯吸波/透波结构，并通过仿真及试验验证力热电耦合分析模型的准确性。最后，基于提出的匹配设计方法，确定结构的几何参数。结果表明，设计的蜂窝夹芯吸波/透波结构有着稳定的宽带宽角吸波/透波性能，在1 000 ℃高温环境下，0°～40°的入射范围内，吸波带宽达4.3 GHz，透波带宽超过1.3 GHz，提出的力热电性能匹配设计方法有利于提升蜂窝夹芯吸波/透波结构的设计水平。

Abstract: The honeycomb sandwich absorptive/transmissive radome structures of high-speed aircraft are subjected to severe mechanical and thermal loads during service. However, current research lacks a matching design study of the mechanical, thermal and electromagnetic performance of absorptive/transmissive structures under high-temperature load-bearing conditions. To ensure stable and excellent mechanical-thermal-electromagnetic performance in high-temperature load-bearing environments, a matching design method for the mechanical-thermal-electromagnetic properties of honeycomb sandwich absorptive/transmissive structures is proposed. Firstly, the influence of mechanical and thermal loads on the mechanical-thermal-electromagnetic performance of a honeycomb sandwich absorptive/transmissive structure is analyzed. Then, a mechanical-thermal-electromagnetic coupling analysis model of a honeycomb sandwich absorptive/transmissive structure is established and an optimization design model for mechanical- thermal-electromagnetic design is constructed. Next, a honeycomb sandwich absorptive/transmissive structure with low-frequency absorption and high-frequency transmission properties is designed. The accuracy of the mechanical-thermal-electromagnetic coupling analysis model is then verified through simulation and experiment. Finally, the geometric parameters of the structure are determined based on the proposed matching design method. The results demonstrate that the designed honeycomb sandwich absorptive/ transmissive structure exhibits stable, broadband, and wide-angle absorptive/transmissive performance. In a high-temperature environment of 1 000 ℃, within an incident range of 0°～40°, the absorption bandwidth is 4.3 GHz and the transmission bandwidth exceeds 1.3 GHz. The proposed method for mechanical-thermal-electromagnetic matching design improves the level of design of the honeycomb sandwich absorptive/transmissive structure.

Key words: mechanical-thermal-electromagnetic coupling analysis, honeycomb sandwich absorptive/transmissive structure, high temperature resistance, mechanical-thermal-electromagnetic matching design
