g Jx)h[l]0【摘要】:Flexible segment model(FSM)is adopted for the dynamics calculation of marine cable being laid.In FSM,the cable is divided into a number of flexible segments,and nonlinear governing equations are listed according to the moment equilibriums of the segments.Linearization iteration scheme is employed to obtain the numerical solution for the governing equations.For the cable being laid,the payout rate is calculated from the velocities of all segments.The numerical results are shown of the dynamic motion and tension of marine cables being laid during velocity change of the mother vessels.
