Best Mast: a new way to design a rig - HISWA Symposium
Hierboven nog een interessant artikel wat vanaf p 5 op de hier besproken krachten in gaat.
Opvallend en wáár:
Current design tools, as until recently used by Nirvana Spars, do not allow for further optimisation of sailing yacht rigs. This is due to the fact that they are based on a simplified statically determined model of the rig and the use of relatively high and often not traceable safety factors to take into account several design uncertainties. Lowering these factors may result in particular cases in unsafe rigs.
To be able to design lighter and reliable rigs in aluminium and carbon, a more sophisticated model for the structural behaviour of a rig is needed. Only a non linear finite element analyses can provide a prediction of this behaviour. This requires a reliable input of the external forces acting on the structure.
Welke tuigers kunnen dit? Anno 2015: worden dezelfde vuistregels als 40 jaar terug gebruikt indien ik bij één van de jachtentuigers in ons land een nieuwe mast laat berekenen?
