摘要

This paper investigates the heating behavior of quartz lamp radiation systems commonly used in hypersonic vehicle thermal balance tests. A finite element simulation model was established and validated through experiments, with a maximum temperature error of 9.69 %. The model was used to analyze the effects of key parameters—such as lamp-to-specimen distance, reflector spacing, lamp spacing, and arrangement angle—on specimen surface temperature and its uniformity. Results show that increasing the lamp-to-specimen distance reduces temperature but improves uniformity. Reducing lamp spacing raises overall temperature while slightly worsening uniformity. A 90° lamp arrangement yields better temperature distribution than a 0° setup. The study provides detailed insights into the influence of structural parameters on thermal field characteristics during quartz lamp heating.
