Abstract

EL SENSOR DE GOLPETEO(10) PARA LA SUJECCION DIRECTA O INDIRECTA A UN MOTOR DE COMBUSTION TIENE UNA CARCASA (30) DE MATERIAL INYECTADO. PARA DESACOPLAR LA MASA SISMICA (19) Y EL PIEZOELEMENTO (16) DE OSCILACIONES MECANICAS PERTUBADORAS SE RODEA LA MASA SISMICA (19) Y EL PIEZOELEMENTO (16) DE UNA CAPERUZA DE GOMA (28). LA CAPERUZA DE GOMA (28) SE COMPONE DE UN MATERIAL MAS BLANDO QUE LA MASA INYECTADA EN LA CARCASA (30). SE ELEVA LA SENSIBILIDAD DEL SENSOR DE GOLPETEO Y SU LINEA DE CARACTERISTICA TRANSCURRE CASI LINEAL.
