Research on Hydrodynamic Model of Nets in Fishing Simulator

摘要：

In order to simulate fishing net’s dynamic behavior in fishing simulator,a hydrodynamic model of fishing nets is established according to lumped mass model,which divides the net into finite mass points connected with springs without mass,and influences of uniform current are taken into account.Calculated positions of mass points instituting variables of position are used to calculate connected mass points’ elastic force,and every mass point’s equations can be solely solved.To take a relative bigger step size for calculation,Newmark-method is used to solve the equations of each mass point.Behaviors of a panel net in uniform current,which proposed by other literature,are simulated,and computation results have been compared with that of flume experiments,which verifies models rationality.
