抄録

Our objective is to develop a numerical calculation method for simulating the three-dimensional dynamic behavior of fishing nets. For the numerical calculation, the fishing nets are modeled as a group of lumped point masses interconnected with springs without mass. Point masses are arranged at each knot or at the center of each mesh bar. Equations of motion for all point masses are derived, and then a net shape can be estimated at each time step by numerically solving these equations. The numerical calculation of the dynamic behavior of a rectangular net in steady flow can provide good results by using the presented formulation. The magnitude of tension force applied to the mesh bars can be observed as the change in the colors of the mesh bars. As a calculated net shape can be viewed as a three-dimensional image from an arbitrary visual point and also the net shape image can be enlarged, the net shape and the tension force distribution can be investigated in more detail.
