摘要: 在实际应用中,吸波蜂窝夹层结构易出现透波蒙皮分层、脱黏和冲击损伤等问题,进而影响其电磁波吸收性能。本文基于一种优化设计的吸波蜂窝夹层结构,建立了含不同典型损伤的仿真分析模型,分析了透波蒙皮分层、蒙皮-蜂窝脱黏以及蒙皮破损等损伤形式对吸波性能的影响,验证了研究结果在不同损伤形状、电磁波入射角度及极化方式下的适用性,最后建立了分层脱黏及蒙皮损伤的吸波蜂窝夹层结构理论模型,详细讨论了损伤对结构吸波性能的影响机制。研究结果表明:分层及脱黏损伤对吸波蜂窝夹层结构在低频带下的吸波性能几乎没有影响,对结构在高频带下的吸波性能甚至有所提升,当损伤直径达到100 mm时,结构的有效吸波带宽最多仅降低了0.06 GHz;透波蒙皮破损则会破坏结构的阻抗匹配特性,使吸收峰向高频移动,导致中高频吸波性能显著下降,当损伤直径达到60 mm时,结构的有效吸波带宽降低了0.6 GHz,平均反射率升高了0.6 dB。

Abstract: In practical applications, wave-absorbing honeycomb sandwich structures are prone to issues such as delamination, debonding, and impact damage of the wave-transmitting skin, which in turn affect their electromagnetic wave absorption performance. Based on an optimally designed wave-absorbing honeycomb sandwich structure, this paper establishes simulation analysis models incorporating different typical damages. It analyzes the impact of damage forms such as delamination of the wave-transmitting skin, skin-honeycomb debonding, and skin damage on the absorption performance. The applicability of the research results under different damage shapes, electromagnetic wave incidence angles, and polarization modes is verified. Finally, a theoretical model of wave-absorbing honeycomb sandwich structures with delamination, debonding, and skin damage is established, and the mechanism by which these damages affect the structural absorption performance is discussed in detail. The research results indicate that delamination and debonding damages have little impact on the absorption performance of the wave-absorbing honeycomb sandwich structure at low frequencies, and even enhance the absorption performance at high frequencies. When the damage diameter reaches 100 mm, the effective absorption bandwidth of the structure is reduced by up to 0.06 GHz; damage to the wave-transmitting skin disrupts the impedance matching characteristics of the structure, causing the absorption peak to shift towards higher frequencies, leading to a significant decrease in absorption performance at mid-to-high frequencies. When the damage diameter reaches 60 mm, the effective absorption bandwidth of the structure is reduced by 0.6 GHz, and the average reflectivity increases by 0.6 dB.
