Abstract
Una cuerda híbrida (40, 50, 60), que comprende un elemento central (42, 52, 62), una primera capa cerrada metálica (44, 54, 64) y una segunda capa cerrada metálica (46, 56, 66) que rodea a dicho elemento central, en la que el elemento central (42, 52, 62), incluye un haz o construcción de hilos sintéticos, la primera capa cerrada metálica (44, 54, 64) incluye una pluralidad de primeros miembros de tipo alambre trenzados juntos helicoidalmente alrededor del elemento central en una primera dirección, la segunda capa cerrada metálica (46, 56, 66) incluye una pluralidad de segundos miembros de tipo alambre trenzados juntos helicoidalmente alrededor de dicho elemento central y dicha primera capa cerrada metálica en una segunda dirección, y en la que el área de la sección transversal del elemento central es mayor que el área de la sección transversal total de la primera capa cerrada metálica (44, 54, 64) y la segunda capa cerrada metálica (46, 56, 66).
Description
acero 54, 56. La cuerda híbrida tiene una construcción de "34+24+FC SZ", lo que significa que la cuerda híbrida tiene un núcleo de fibra, teniendo la primera capa metálica una dirección de rotación de "S" con 24 hilos y la segunda capa metálica con una dirección de rotación de "Z" que tiene 32 hilos. Los detalles de algunas de las posibles construcciones de cuerda híbrida se dan en la tabla 2. Se debe entender que las capas metálicas también pueden comprender una combinación de hebras de filamento e hilos de acero individuales.

sintética para estas aplicaciones (Del Vecchio CJM, 1992, Light-weight materials for deep water moorings, PhD thesis University of Reading; Francois M, Davies P, 2008, Characterization of polyester mooring lines, OMAE 200857136). Los ensayos para determinar la rigidez cuasi-dinámica se llevan a cabo como se define en los estándares internacionales (ISO 18692, 2007, cuerdas de fibra para el mantenimiento de estaciones en alta mar -poliéster) y reglas de las sociedades de clasificación (Bureau Veritas, 2007, Certificación de cuerdas para servicios en alta mar en aguas profundas, NI432R01).
El esquema de carga para la medición cuasi-dinámica se muestra en la Fig.7. La abscisa es el tiempo en la unidad de segundo(s) y la ordenada es la carga aplicada en la unidad de kN. La carga media aplicada es 10 %, 20 %, 30 % y 40 % de la carga de rotura (BL) de la cuerda de alambre. Los valores de rigidez cuasi-dinámica de la cuerda híbrida (A) y de la cuerda toda de acero (B) se muestran y comparan en la Fig. 8. La rigidez cuasi-dinámica de las dos cuerdas se incrementa significativamente con el aumento de carga media sobre el rango de cargas aplicadas (10 a 40 % de BL). La rigidez cuasi-dinámica de la cuerda híbrida (A) es 17-26 % más baja que la de la cuerda de todo acero (B). Sin embargo, la ventaja de la cuerda híbrida respecto a la cuerda de acero aparece cuando se tiene en cuenta el peso. La rigidez específica se define como la relación entre rigidez y peso lineal. Como se muestra en la Fig. 9, la rigidez específica de la cuerda híbrida (A) es 22 a 37 % mayor que la de la cuerda toda de acero (B) en el rango de carga ensayado.
Además, en la Fig. 10 se evalúa la deformación por fluencia lenta con el tiempo a cargas constantes. La deformación por fluencia lenta se define como la deformación (elongación) de la cuerda de acero bajo una situación de carga constante, estática. Una cuerda híbrida multi-hebra de 22 mm (A) se compara con la cuerda toda de acero de 8 hebras de 13 mm (C) y con la cuerda híbrida de 8 hebras de 13 mm (D). La carga aplicada a la cuerda híbrida multihebra de 22 mm (A) es 50 % BL, mientras que la cuerda toda de acero de 8 hebras de 13 mm (C) y la cuerda híbrida de 8 hebras de 13 mm (D) es del 40 % BL. Las temperaturas de la cuerda de alambre se mantuvieron a aproximadamente 50 ºC durante la medición de 10 días. La deformación lenta por fluencia se midió como un cambio de la tensión (%) a lo largo del tiempo (h). Como se muestra en la Fig. 10, la cuerda híbrida (A) presenta una tensión mayor que la cuerda toda de acero (C) en el momento de la aplicación de la carga, que es lo que cabría esperar de una cuerda con núcleo de fibra. Sin embargo, con el tiempo y a carga constante, la cuerda híbrida (A) muestra un cambio de tensión similar en comparación con la cuerda de alambre toda de acero (C). En comparación con la cuerda híbrida de 8 hebras (D), se aplica más carga en la cuerda híbrida multi-hebra de la invención (A) (50 % frente a 40 % BL). Además, el área de sección transversal relativa del núcleo es más grande en la cuerda híbrida multihebra (A). Incluso con estos hechos, la relación entre deformación por fluencia lenta de la cuerda multi-hebra (A) es significativamente baja. Por lo tanto, la deformación por fluencia lenta no es se convierte en un problema con el tiempo en el caso de la cuerda híbrida de la invención.
