S20  Vibroacústica    Titulo: FLUXO DE ENERGIA DO CONJUNTO MOTO-COMPRESSOR PARA A CARCAÇA ATRAVÉS DA CAVIDADE DE UM COMPRESSOR HERMÉTICO   Resumo : ABSTRACT. HERMETIC COMPRESSORS AS USUALLY USED IN DOMESTIC REFRIGERATION SYSTEMS ARE RESPONSIBLE FOR MOST OF THE NOISE RADIATED BY SUCH SYSTEMS. THERE ARE SEVERAL INTERNAL MECHANISMS OF NOISE GENERATION, SUCH AS THE LARGE AND RAPID GAS PRESSURE VARIATIONS IN THE CYLINDER, CAUSED BY THE INTERMITENT GAS FLOW ADMITTED TO THE CYLINDER. THIS WORK DEALS WITH THE VIBRATION ENERGY TRANSMISSION FROM THE INTERNAL MOTOR PUMP ASSEMBLY TO THE CASING THROUGH THE CAVITY, FILLED WITH GAS. NUMERICAL ANALYSES BASED ON FINITE ELEMENTS MODELS INDICATE THE RELATIVE IMPORTANCE OF THE ASSEMBLY VIBRATIONS TO THE OVERALL NOISE RADIATED.
