摘要：
Taking the point focus solar furnace as the research object，the optical-structural coupling is proposed，and the simulation calculation model of energy flow density distribution is established. The flux density simulation distribution analysis is carried out under the ideal conditions，considering the action of gravity and wind load and the measured surface condition of the solar furnace，and the measured research of flux density distribution is carried out. The results show that for the solar furnace system，the influence of gravity on the concentrating performance is small，about 5%；The installation error and wind-induced deformation have a great impact on the condensing performance，about 11% and 25%，respectively. Through the comparison between theoretical prediction and experimental results，it is proposed to correct the error factor of concentrator in the software prediction model by 9 mrad. © 2023 Science Press.
