Abstract

UN DISPOSITIVO DE VIBRACION QUE CONSTA DE UN ALOJAMIENTO (12) QUE TIENE UNA CAVIDAD CENTRAL (20) Y UN PARA DE CAVIDADES LATERALES (22, 24) CON UNA DIMENSION RADIALMENTE MENOR QUE LA DE LA CAVIDAD CENTRAL, EXTENDIENDOSE TODAS ELLAS AXIALMENTE ALREDEDOR DE UN EJE (26) DESDE LOS EXTREMOS OPUESTOS DE LA CAVIDAD CENTRAL. DENTRO DE LAS CAVIDADES (20, 22, 24) HAY ALOJADO UN PISTON (50) E INCLUYE UNA MASA (52) DISPUESTA DENTRO DE LA CAVIDAD CENTRAL (20) Y UN PAR DE SOPORTES (54, 56) DISPUESTOS DENTRO UNA CAVIDAD RESPECTIVA DEL PAR DE CAVIDADES (24, 22) Y QUE SE EXTIENDEN AXIALMENTE DESDE LA MASA. LOS SOPORTES (54, 56) TIENEN UNAS DIMENSIONES RADIALES SUSTANCIALMENTE IGUALES A LAS DEL PAR DE CAVIDADES (22, 24). LA MASA (52) Y LOS SOPORTES TIENE DIMENSIONES AXIALES SUSTANCIALMENTE MENORES QUE LOS RESPECTIVOS DE LA CAVIDAD CENTRAL Y DEL PAR DE CAVIDADES (20, 22, 24) PARA PERMITIR QUE EL PISTON (50) SE MUEVA AXIALMENTE DENTRO DE LAS CAVIDADES. UNOS ORIFICIOS PARA LA ENTRADA DEL AIRE (61, 62) QUE HAY ENEL ALOJAMIENTO Y UNOS CONDUCTOS (66, 68) EN EL PISTON PERMITEN QUE EL PISTON OSCILE DENTRO DEL ALOJAMIENTO PARA EJERCER UN IMPACTO REPETITIVO CONTRA UN IMPACTOR (38) PARA LA TRANSMISION DE LA ENERGIA ASI OBTENIDA A UNA MESA DE ENSAYO Y A UN ELEMENTO BAJO ENSAYO.
