Etude dynamique d'un train de pêche complet
We present a complete numerical model of a full trawl gear and the vessel. The trawler is modelled by equations and hydrodynamic coefficients which are classically used for ship behaviour and ship manoeuvrability studies. It is submitted to the action of the warps. The warps and the net are part of a complex fluid-structure coupling problem. The net is a supple structure and its shape depends on the forces that are acting on it. Now, these forces themselves depend of the net meshes shape. The otter boards are most particular wings. We have studied one particular type. Then all these elements have been put together by writing their dynamics equations. A time step method enables the calculation of the shape, the forces and the motion of each element in the whole system.
