THE TRANSVERSE VIBRATION OF HIGHLINE CABLE OF ALONGSIDE REPLENISHMENT SYSTEM

摘要

A theoretical model for transverse vibration of highline cable of alongside replenishment system at sea was acquired by elasticity mechanics principle, which considered the effect of the concentrated mass of highline cable. The partial differential equation was discretized into ordinary differential equation by Galerkin method, the standard nonlinear dynamic controling equation of highline cable was acquired by ignore the influence of high order model. The dynamic equation was asymptotically analyzed by muti-scale method. The results show that the factors which influence the dynamic behavior of highline cable transverse vibration include the external excitation, the position of concentrate mass on highline cable and the length of highline cable.
