Abstract

UN DISPOSITIVO PARA AMORTIGUAR VIBRACIONES INCLUYE UN PRIMERO Y UN SEGUNDO MIEMBROS EXTREMOS (2,5) SEPARADOS AXIALMENTE, ADAPTADOS PARA SER MONTADOS SOBRE ESTRUCTURAS SEPARADAS APARTE. UN MIEMBRO INTERMEDIO (15) ESTA MONTADO DENTRO DE UN EXTREMO ABIERTO DEL SEGUNDO MIEMBRO EXTREMO. UN MIEMBRO CENTRAL (26) COMPUESTO DE UN TUBO RIGIDO (27) QUE TIENE UN AGUJERO (31) Y UN PISTON DE BAJADA (28) ESTA CONECTADO AL PRIMER MIEMBRO EXTREMO (2) Y SE EXTIENDE A TRAVES DEL INTERIOR DEL MIEMBRO INTERMEDIO (15). EL TUBO FORMA UN ORIFICIO ANULAR QUE SE EXTIENDE ALREDEDOR DE UNA VARILLA ELECTRODO RIGIDA (60) QUE SE PROLONGA A TRAVES DEL TUBO RIGIDO Y QUE TAMBIEN ESTA CONECTADA AL PRIMER MIEMBRO EXTREMO Y AL PISTON, PERO AISLADA ELECTRICAMENTE DE ELLOS. UN PAR DE CASQUILLOS DE ELASTOMERO (45,53) SE EXTIENDEN ENTRE EL MIEMBRO INTERMEDIO Y EL PRIMER MIEMBRO EXTREMO Y ENTRE EL MIEMBRO INTERMEDIO Y EL PISTON PARA FORMAR UN PAR DE CAMARAS DE FLUIDO (51,58) QUE COMUNICAN CON EL ORIFICIO Y ADAPTADAS PARA CONTENER UN FLUIDO ELECTRORREOLOGICO. CADA UNO DE LOS CASQUILLOS TIENE UNA OREJETA DE RODADURA (50,54) CON CENTROS CIRCULARES Y DIFERENTES RADIOS DE CURVATURA. SIN EMBARGO, LOS CENTROS CIRCULARES DE LAS OREJETAS DE RODADURA ESTAN SOBRE UN CILINDRO IMAGINARIO COMUN QUE SE EXTIENDE AXIALMENTE, POR LO QUE LAS SUPERFICIES EFECTIVAS DE LAS CAMARAS DE FLUIDO PERMANECEN SUSTANCIALMENTE IGUALES CUANDO EL DISPOSITIVO SE MUEVE ENTRE POSICIONES DE UNION Y DE REBOTE PARA REDUCIR EL EFECTO DE REGIMEN DE MUELLE SOBRE EL AMORTIGUADOR. INCLUSO AUNQUE LAS OREJETAS DE RODADURA TIENEN LOS MISMOS CENTROS CIRCULARES, LOS RADIOS DE LAS OREJETAS QUE FORMAN PAREDES SON DIFERENTES, LO QUE PERMITE EL ENCAJADO DEL PISTON DENTRO DEL MIEMBRO INTERMEDIO PARA REDUCIR LA ALTURA AXIAL DEL DISPOSITIVO SIN AFECTAR A SU LONGITUD DE CARRERA.
