大型豪华邮轮泵控式抗横倾系统仿真分析

Simulation analysis of the pump-controlled anti-heeling system for large cruise ships

为了分析邮轮调整静态横倾角的能力,本文以某大型豪华邮轮抗横倾系统为研究对象,建立了泵控式抗横倾系统Simulink模型及Flowmaster动态节点模型,给出了以Simulink结果作为Flowmaster输入条件联合仿真的方法,仿真分析了邮轮在不同初始角条件下调整横倾角的能力,并对可调整的最大角度与邮轮技术要求进行了对比。研究结果表明:对象邮轮发生静态横倾时可在11.83 min内调整2.73°满足技术要求;动态节点模型调整邮轮静态横倾角所需时间,与Simulink的计算结果相比误差为0.12%,可知Simulink计算出的结果作为Flowmaster模型输入条件联合仿真的方法是可行的;Flowmaster动态节点仿真可将三维结果可视化,对于分析邮轮抗横倾系统的实时工作状态具有借鉴意义。

A pump-controlled anti-heeling system,including the Simulink model and Flowmaster dynamic node model,is established for the anti-heeling system of a large luxury cruise ship to analyze the capability of the cruise ship to adjust the static heeling angle.A joint simulation method with Simulink results as the input conditions of Flowmaster is introduced.The capability of a cruise ship to adjust the heeling angle under different initial angles is simulated and analyzed,and the adjustable maximum angle is compared with the technical requirements of the cruise ship.Research results show that when the target cruise ship undergoes static heeling,it can adjust the heeling angle to 2.73°within 11.83 min to meet the technical requirements.Compared with the results calculated by Simulink,the error of the time required by the dynamic node model to adjust the static heeling angle of the cruise ship is 0.12%.Therefore,using the results calculated by Simulink as the input conditions of the Flowmaster model for joint simulation is feasible.Flowmaster dynamic node simulation can visualize the three-dimensional results as a reference to analyze the real-time working status of the anti-heeling system of a cruise ship.
