Abstract: Aiming at the requirement of accurate simulation of non-uniform thermal environment in structural thermal test, a fast power optimization method of quartz lamp array based on the linear analysis model is established, based on the theoretical analysis of heat flux distribution of quartz lamp array. The power optimization of non-uniform aerodynamic heating simulated by quartz lamp array is analysed. The results show that the linear analysis method can optimize the power of quartz lamp arrays efficiently and effectively, obtain good results for the gentle heat flux distribution, and obtain the accordant heat flux optimization results as the genetic algorithm for the large gradient heat flux distribution. Since the power optimization results of non-uniform aerodynamic heating simulation are sensitive to the heat flux input, it is necessary to select the appropriate range and number of measuring points to obtain a relatively stable coefficient matrix. The results are of important reference significance for the power optimization of quartz lamp array that simulating non-uniform aerodynamic heating.
