本文研究了航天器用網(wǎng)格面板蜂窩夾層結(jié)構(gòu)的紅外熱像檢測技術(shù)。該技術(shù)首先利用紅外相機對航天器表面進行掃描，獲取其熱量分布圖像。然后，通過對熱量分布圖像的解析，分析表面及下層結(jié)構(gòu)的熱傳導(dǎo)性能，以便檢測可能存在的結(jié)構(gòu)缺陷。本研究在不同環(huán)境溫度下對不同種類的航天器網(wǎng)格面板蜂窩夾層結(jié)構(gòu)進行了紅外熱像檢測實驗，設(shè)計了基于多項式回歸的熱傳導(dǎo)擴散方程式，對實驗結(jié)果進行了深入分析。最終得出了有效的航天器網(wǎng)格面板蜂窩夾層結(jié)構(gòu)紅外熱像檢測技術(shù)，為航天器安全運行提供了重要保障。
