| Abstract: | This paper presents the simulation of heat flux on complex-shaped lunar detector in thermal tests.The optimization design of infrared lamp array is realized by using duel-objective and variable metric grid strategy based on genetic algorithm and complex algorithm.The heat flux distribution database is generated based on the calculation of the heat flux distribution of a single lamp.The problem of the heat flux reflection from the reflective baffles is thus solved.A simulation method for calculating the infr... |
