Mathematical modeling of the trim of a fishing vessel when purse seine sampling
When working fishing vessel with a purse seine, the stages of setting a seine, seine pursing, sampling a seine are distinguished. The sampling process requires special attention, seance at the same time, significant forces affect the sinner from the fishing gear, affecting the trim of the vessel. A physical model has been developed that takes into account the interaction of a fishing vessel and a purse seine. It takes into account the points of application of the tension forces of the cables coming from the seiner inches to the fishing gear, the parameters of the purse seine. The seine sampling process is stationary, the loads are quasi static. A mathematical model has been developed that allows to find the time parameters. An example of calculation is given. The dependence of the change in the angle of the trim on the tension force of the tie cable at different lifting values of the rosin block are obtained.
