S8  Engenharia Aeroespacial    Titulo: NUMERICAL RESULTS FOR A COUPLED LAUNCHER-SATELLITE SYSTEM ANALYSIS   Resumo : THIS PAPER PRESENTS SOME PRELIMINARY NUMERICAL RESULTS OBTAINED FOR THE ANALYSIS OF A COUPLED LAUNCHER-SATELLITE SYSTEM, NAMELY THE FIRST BRAZILIAN LAUNCHER, THE VLS, AND ITS SATELLITE. THE FINITE ELEMENT METHOD IS USED TO OBTAIN THE RESPONSE OF THE SYSTEM. THE LAUNCHER IS MODELED AS A 3-D BEAM-LIKE STRUCTURE, WHERE BEAM ELEMENTS, LUMPED MASSES AND SPRING ELEMENTS WERE USED. EXPERIMENTAL MODAL ANALYSIS RESULTS WERE USED TO ADJUST THE FINITE ELEMENT MODEL OF THE VEHICLE. THE SATELLITE IS REPRESENTED BY A FULL 3-D MODEL. A CURVE OF THRUST AS FUNCTION OF TIME IS USED TO INPUT THE DYNAMIC LOAD ONTO THE SYSTEM. RESPONSES AT SPECIFIC LOCATIONS ARE GIVEN IN BOTH TIME AND FREQUENCY DOMAINS. IN THE ACTUAL VEHICLE, ACCELEROMETERS ARE USED TO TAKE MEASUREMENTS DURING FLIGHT. FUTURE FLIGHTS OF THE VEHICLE WILL GENERATE DATA THAT WILL ALLOW THE EVALUATION OF THE REALIBITY OF THE MODEL.    Autores : Damilano, J. G. Duarte, J. A.
