Abstract

EL SOPORTE (17) QUE FORMA EL EQUIPO TIENE UN DIAMETRO DE UN ORDEN DE MAGNITUD SUPERIOR A SU PROPIA ALTURA, DE UN ORDEN DE MAGNITUD SUPERIOR A SU ESPESOR. ESTE ESTA RIGIDIZADO POR DOS MEMBRANAS, CADA UNA DE LAS CUALES ESTA FORMADA POR UNA VIROLA COMPUESTA QUE INCLUYEN, ENTRE EL SOPORTE (17) Y UN ACORONA RIGIDA CONCENTRICA (23,24), UN ANILLO ELASTOMERICO (22) ADHERENTE QUE TIENE UNA ALTURA AXIAL DE IGUAL ORDEN DE MAGNITUD QUE SU ESPESOR RADIAL. ESTOS ANILLOS PROPORCIONAN, POR UNA PARTE, EL RETROCESO ELASTICO DEL SOPORTE EN DESPLAZAMIENTO AXIAL Y, POR OTRA, EL MANTENIMIENTO DE LA FORMA CIRCULAR Y, EN CONSECUENCIA, DE LA FORMA PLANA DE DICHO SOPORTE.
