大型船舶倒车制动性能实用预报方法

摘要

为了安全航运,船舶驾驶员通常借助于倒车实施紧急制动进行避让、泊入锚地或靠离码头.文章基于船舶制动运动数学模型,应用”速度线性递减”假定,建立了船舶在各种工况下的制动性能的预报方法.通过实例计算和试验结果的比较可知,该预报方法可用于船舶在各种航速、各种功率下的制动性能预报,为驾驶人员提供实施操纵作业的技术参考.%For safety the ship drivers usually perform astern stopping by inversing propeller to avoid collision, moor to its berth, dock or undock. In this paper, the predicion method of astern stopping is established, based on mathematical model of astern stopping motion and applying supposition of ' linear degression for velocity' .The comparion of calculation results and test results shows that the prediction method can be applied for the astern stopping performance in any speed and any power, which will direct the ship drivers to carry out the mode of steering.
