【摘要】：海洋经济的快速发展带来了对包括工作船在内的各类船舶的新需求。但在倡导绿色航运的今天,对船舶的排放要求也变得日益严格。工作船因不受国际海事组织(IMO)严格排放法规的约束,其排放已成为危害港口地区大气环境的最大污染源。因此,国家出台了多项法规限制此类船舶的排放,这给行业发展带来了新的挑战。要解决船舶排放造成的环境污染首先想到的就是提高柴油机的效率来控制船舶的废气排放,这对于现代船舶是远远不够的。本课题从节能实现减排的方向,对能造成能量损失的船、机、桨三方面进行优化,以期提高船舶整体的能效水平,从源头上实现符合法规要求的减排、治污目标。本课题分三个部分进行研究。第一部分是某工作船的设计。根据其使用要求,使用MAXSURF对船型进行优化并完成其阻力预报;第二部分是工作船选用柴油机的增压优化。使用AVL-Boost对柴油机进行仿真运算分析,得到其匹配涡轮增压器的最佳选择方案;第三部分首先分析船舶的能量传递损失,并讨论适于本船的合理、高效的动力装置布置方案,然后根据船、机的实际性能指标选择合适的桨型,通过计算完成满足船舶使用要求的最佳匹配的螺旋桨选型。与此类船舶长期采用经验法、实物匹配法以满足适用为准则进行的设计选型相比,本课题的研究方案更具有直接现实意义。其设计流程和理论观点也可为今后此类船舶设计选型提供借鉴。
[Abstract]:The rapid development of marine economy has brought a new demand for all kinds of ships, including working ships. But today, when green shipping is advocated, The discharge requirements of ships are becoming more and more stringent. Since the working ships are not subject to the strict emission regulations of the International Maritime Organization (IMO), their discharge has become the largest source of pollution that endangers the atmospheric environment in port areas. The country has issued a number of regulations to limit the emission of such ships, which has brought new challenges to the development of the industry. To solve the environmental pollution caused by ship emissions, the first thought is to improve the efficiency of diesel engines to control the exhaust emissions of ships. This is far from enough for modern ships. In order to improve the overall energy efficiency of the ship, this subject optimizes the ship, engine and propeller which can cause energy loss in the direction of energy saving and emission reduction. This thesis is divided into three parts to study. The first part is the design of a working ship. According to its use requirements, MAXSURF is used to optimize the ship form and complete its resistance forecast. The second part is the turbocharging optimization of the diesel engine for the working ship. The simulation analysis of the diesel engine is carried out by using AVL-Boost, and the optimal scheme of matching turbocharger is obtained. In the third part, the energy transfer loss of the ship is analyzed. The reasonable and efficient power plant arrangement scheme suitable for the ship is discussed, and then the suitable propeller type is selected according to the actual performance index of the ship and the engine. The optimal matching propeller selection that meets the requirements of ship operation is completed by calculation. Compared with the design selection of this kind of ship which is based on the criterion of application and experience, the physical matching method is adopted for a long time. The research scheme of this subject is of direct practical significance, and its design flow and theoretical viewpoint can also be used for reference for the design and selection of this kind of ship in the future.
