Experimental validation of a numerical model for non contact, massively actuated, deformable adaptive mirrors

摘要

The validation of the multidisciplinary model of a deformable, massively actuated adaptive mirror is presented. The related experimental correlations are focused on an adaptive shell with 45 non contacting voice coils actuated points, dubbed P45, that was developed as an engineering verification prototype for the LBT adaptive secondary mirrors. A description of the multi physics model is followed by the results obtained simulating actual experimental tests and by their correlation with the related true measures. The significance of various modeling details and their impact on the correlation is discussed. The results show a remarkable match between numerical and experimental data.
