Última Etude dynamique d'un train de pêche complet ArchiMer Marichal, Dominique; Vincent, Benoit. 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...

A complete method is presented for determining the static and dynamic behaviour of a fishing gear. The net, which is very flexible, is modelised by a set of rigid bars. The hydrodynamic forces, applied to each bar, are determined by combining and generalizing the Landweber and Morison hypothesis. A CFD method is used to calculate the forces on trawl doors. The fundamental principle of dynamics is completed with length equations expressing the elasticity of the bars. It leads to a set of second order non-linear differential equations, which is solved using a Runge-Kutta method. We will now present a few examples of the various applications of our works : the study of the trawl gear equilibrium in a uniform flow, an example of manoeuvrability (gyration of...
