Abstract

UN SISTEMA AISLADOR (20) QUE COMPRENDE LA COMBINACION DE UNA MONTURA ELASTOMERICA (25) PARA ACOPLARLA ENTRE UNA ESTRUCTURA (24) Y UN MIEMBRO VIBRATORIO (22) Y QUE COMPRENDE ADEMAS AL MENOS UN AMORTIGUADOR DE VIBRACIONES SINTONIZADO PASIVO (TVA) (32) ACOPLADO CERCA DE LA MONTURA ELASTOMERICA (25) PERO SOBRE EL LADO DE LA ESTRUCTURA DE LA MISMA. LA FRECUENCIA RESONANTE F R DEL TVA PASIVO (32) SE SINTONIZA A UNA FRECUENCIA RESONANTE F R JUSTO POR DEBAJO DE UNA FRECUENCIA OPERATIVA P REDOMINANTE F O DEL MIEMBRO VIBRATORIO (32) DE MODO QUE LA RESONANCIA DEL AMORTIGUADOR DE VIBRACIONES SINTONIZADO (32) HAGA QUE LA ESTRUCTURA (24) PAREZCA MAS CONSISTENTE DINAMICAMENTE. EN PARTICULAR LA RELACION DE F R /F O ES DE 0,90 APROXIMADAMENTE Y 0,99. EN UNA REALIZACION DE LA INVENCION, EL TVA PASIVO (32) SE ACOPLA DIRECTAMENTE AL MIEMBRO INTERIOR (28) DE LA MONTURA ELASTOMERICA (25) Y SE SUJETA EL CONJUNTO DEL TVA (43) A LA ESTRUCTURA Y SE FIJA LA ESTRUCTURA (24) A LA MONTURA ELASTOMERICA (25). EN OTRA REALIZACION DE LA INVENCION, EL TVA PASIVO (32) SE FIJA A LA ESTRUCTURA (24) EN UN PUNTO EN EL QUE COOPERA CON LA MONTURA ELASTOMERICA (25) PARA REDUCIR LA VIBRACION TRANSMITIDA, QUEDANDO EL TVA (32) ACOPLADO PREFERENTEMENTE EN UN PUNTO DENTRO DEL ULTIMO 20 % DEL EXTREMO DE LA ESTRUCTURA TIPO VIGA (24).
