Abstract

Abstract: To reflect and simulate the flow condition and ship attitude in mountainous river, a 3-DOF ship motion mathematical model based on open channel non-uniform flow and shallow water effect is put forward. Analysis of the numerical simulation shows that with the decrease of depth-draft ratio h/d, the ship direct navigation speed decreases, the shallow water effect and the turning diameter increases. Meanwhile, the Z motion fluctuation amplitude and the oscillation period increase with the decrease of h/d, which means the decrease of the rudder effect and maneuverability. Application of the model in a case study shows that the proposed model can be applied in the engineering research. It is more rational and practical to achieve the ship maneuverability model based on open channel non-uniform flow and shallow water effect.

Key words: waterway engineering, non-uniform flow, shallow water effect, ship maneuverability, ship motion mathematical model
