The optimized design for improving flux uniformity of infrared lamp array

摘要: 真空熱試驗中通常使用紅外燈陣作為整星試驗和太陽電池板試驗的外熱流模擬裝置。文章從平面燈陣的研究出發(fā)，建立了使用紅外燈陣作為外熱流模擬裝置時到達被加熱面熱流密度的計算模型，對影響熱流密度均勻性的因素進行了分析，提出了紅外燈陣優(yōu)化設(shè)計方法，以提高熱流模擬時衛(wèi)星表面的熱流密度均勻性。研究結(jié)論可以用于指導(dǎo)真空熱試驗所用紅外燈陣的工裝設(shè)計。

Abstract: The infrared lamp array is usually used for simulating the external thermal flux in the test of spacecraft and solar array. A model is set up in this paper to calculate the flux uniformity on the spacecraft surface where the infrared lamp array is used for the flux simulation. Factors that affect the flux uniformity of a planar infrared lamp array are analyzed, and some methods of optimizing the design are proposed to improve the flux uniformity on the spacecraft surface. Those methods can provide guidance for the design of the infrared heating cage used in spacecraft vacuum thermal tests.
