基于运动学的船舶过闸时间模型

摘要

The ship lock time is analyzed, and obtained the key is the elastic time calculation. By the measured data of one northern lock of the Grand Canal utilizing and the relationship between the length of the ship and tonnage and the Greenshields model of the traffic flow theory combining a kinematic calculation method of the ship lock time is proposed. It expresses and calculates the lock time of mixed ship better with universality, and it can be used to predict or estimate the possible passing capacity and optimize scheduling of the ships.%通过对船舶过闸时间的解析,得到船舶过闸时间计算的关键在于弹性时间的计算,并利用京杭运河苏北段某梯级船闸的过闸数据,结合船舶长度和吨位的关系及交通流理论中的Greenshields模型,提出了船舶过闸时间的运动学计算方法,该方法较好地表达和计算了混合船型船舶的过闸时间,具有普适性,也可用于预测或估计船闸的可能通过能力及优化船舶调度.
