摘要/Abstract

摘要： 为更好体现和模拟山区河道的水流条件和船舶航行姿态,在明渠恒定非均匀水流模型基础上,开发了基于浅水效应的3自由度MMG船舶操纵运动数学模型。通过船舶定回转试验和Z型运动模拟结果表明,随着水深吃水比h/d的减小,船舶浅水效应越为突出,直航速度越小,定回转直径越大;同时,船舶Z型运动的摆幅越大,运动周期越长,说明船舶的舵效和操纵性能越差。结合工程实例分析表明,本文开发的基于非均匀流和浅水效应的船舶操纵运动数学模型可以应用于工程实际研究,山区河道的船舶操纵运动采用基于浅水效应的模型计算才更加合理和符合实际。

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
