USE OF VIRTUAL TESTING FOR EQUIPMENTS QUALIFICATION TESTS AND THERMAL MODEL VALIDATION IMPROVEMENT

摘要

The simulation becomes more and more importantduring equipment conception in order to reduce risksand time.The more accurate is the model, the more risksreduction will be effective.The model accuracy is improved by comparisonbetween test and calculation results.As a consequence, the development of virtual testingleads to thermal model validation improvement but alsoto equipment behaviour prediction for qualificationtests.The study performed by Intespace is a numericalthermal analysis of a climatic chamber, and a virtualqualification test for equipment [2].The first goal of the study is to use the qualification testresults at equipment level in order to support updatingand validate the equipment model. The second objectiveof the study is to use the validated test facility model inorder to criticize the limitations of the standard [2]requirements. The last goal of the study is to use thevalidated equipment model in order to predict hisbehaviour in flight environment conditions, to define theworst case conditions for the equipment and to predictits behaviour in worst case conditions.
