摘　　要：为提高船舶机舱通风管系三维设计效率,减少设计优化过程中的建模和改模工作量,以某油船为研究对象,运用三维设计软件CATIA,基于自顶向下的设计理念进行机舱通风管系三维设计。结合计算流体力学(CFD)数值模拟法对设计的合理性进行分析,并根据分析结果进行三维设计优化。研究表明,基于自顶向下设计理念的船舶机舱通风管系三维设计方法能满足设计优化带来的模型快速变更需求,相比传统的基于自底向上设计理念的设计方法,能显著提高设计优化迭代的速度,降低三维设计成本。该方法可供船舶机舱通风管系设计参考。In order to improve the efficiency of the three-dimensional(3D)design of the engine room ventilation piping of the ship and reduce the workload of modeling and modification in the process of design optimization,the 3D design software CATIA was used to carry out the 3D design of the engine room ventilation piping based on the top-down design concept,combined with the numerical simulation method of computational fluid dynamics(CFD),the rationality of the design was analyzed,and the 3D design optimization was carried out according to the analysis results.The results showed that the top-down 3D design method can meet the rapid model change requirements brought about by design optimization,and can significantly improve the speed of design optimization iteration compared with the traditional bottom-up design method.The top-down reduced the 3D design cost,combined with CFD numerical simulation,can provide an effective reference for the design of the engine room ventilation piping.
