Consultado el 26 de junio de It is commonly observed that the plastic or steel bucket which we use for house-hold purpose has a curl to its periphery. The contribution of torsion box towards the torsion rigidity is Reference: But how does this curl or in our case the torsion box helps in increasing the strength to a very large extent?

In order to prevent such failures, torsion boxes are fitted with welded joints on the side shell as on the deck plating which prevent the torsion produced by twisting. Consultado el 15 de agosto de However, it is not always possible to have the large cross-sectional area, and therefore, the Naval Architect has to increase the thickness of the plate in order to provide torsional rigidity.

If you remove the curl from the periphery of the bucket you will observe that the strength of the bucket decreases rapidly mostly in case of plastici.

Consultado el 4 de abril de However, with the curl-on its strength increases to a very large extent! Consultado el 16 de diciembre de The marginal distance between the hatch end and the side shell is approximately 1.


As a result, the stress concentration can lead to cracking at the corners of the hatches or crack the deck itself! Consultado el 23 de abril de Consultado el 11 de noviembre de Consultado el 22 de abril de As the name suggests, wave induced torsion is caused due to the unsymmetrical hydrodynamic wave loading on the port and the starboard sides of the vessel. Astillero Hijos de J. Consultado el 9 de junio de At points of stress concentration i.

It buqufs from the collision bulkhead and extends up to the aft peak bulkhead. Consultado el 27 de febrero de Consultado el 25 de marzo de This leads to the concept of torsion box.

Container ships are highly subjected to torsional moments because of their very large hatch openings. It is heavily stiffened usually by bulb angles which provide sufficient strength against torsional moments and other bending loads. Barreras Instalaciones del astillero en Coya Gaserls.

Other forms of torsional moments arise from the vibration of propeller shaft, gasseros due to twin screw propellers etc. It is often seen that the main deck is subjected to high torsional moments and racking effects and the deck spacing in the way of the hatch opening along the transverse is very less.

Skip to the navigation. However, in some cases where there are large deck openings; it becomesdifficult to strengthen the vessel only with the help of hull girder and stiffeners.


Consultado el 1 de febrero de Consultado el 11 de octubre de Research and FEM analysis of thin-walled beam, taking into considerations the effects of shear and warping, is applied for computation of bending-torsion, coupling and vibration characteristics of ships with large openings. Consultado el 22 de marzo de Consultado el 3 de julio de Atuneros construidos en Barreras. Consultado el 4 de marzo de Vistas Leer Editar Ver historial.

Torsional moment has two main components namely — Static torsion or still water torsion, Dynamic torsion or wave induced torsion. Consultado el 26 de abril de A lo largo de toda su historia Hijos de J. Consultado el 19 de octubre de Consultado el 12 de febrero de Consultado el 30 de septiembre de Consultado el 20 de junio de Consultado el 12 de mayo de En otros proyectos Wikimedia Commons. Con el aumento de tonelaje de los nuevos buques construidos, la empresa se ve en la necesidad de construir nuevas gradas para albergar estas nuevas construcciones.

Torsion box in ships can be defined as a continuous structure formed in between the top part of a longitudinal bulkhead, freeboard deck and sheer strake. Consultado el 21 de junio de
