Abstract: The ballast system is the core system of the naval ship to implement attitude adjustment during the various loading conditions. The control of the operation time is critical to the system design. It focuses on the ballast system combing gravity water filling and the pump water filling. The dynamic calculation of the operation time for the single-tank and multi-tanks gravity water filling that varies with the liquid level in the ballast tank and the hull waterlines are studied based on the law of energy conservation and the law of mass conservation. The artificial prediction strategy is proposed for the transformation from the gravity water filling to the pump water filling. It can provide reference for the calculation and application of the full-scale ships.

摘要： 压载系统是舰船实现各种任务工况姿态调整的核心系统,系统设计关键在于作业时间控制。以重力浸水及泵注水结合型式的压载系统为研究对象,基于能量守恒定律和质量守恒定律为理论基础,研究单舱重力浸水、多舱同时重力浸水作业时间随压载舱内液位及船体水线变化的动态计算方法,提出重力浸水向泵注水转变人工预判策略,可供实船计算应用参考。
