The optic-thermal coupling effect evaluation system for aerospace materials is mainly used to simulate the environment of solar radiation with different intensities in a constant-pressure and temperature-varying environment to test the photochemical effect and optic-thermal effect tolerance of aerospace materials. This paper introduces the key design and numerical simulation results of the system. The results show that the temperature and radiation intensity range of system is sufficient to meet the test requirements of the national military standard. The deviation between the temperature setting value and the measured value is within 0.5°C, and the light deviation is less than 5%.
