| 摘要:针对某型常规港作拖轮89%工作时间主机工作在30%以下的低负荷工况，导致排放差、油耗高的问题，基于该船定距舵桨条件，开展柴电混合动力推进系统的设计。经过船模试验的航速和拖力预报显示:所设计的动力系统满足技术要求。基于定距舵桨的柴电混合动力系统设计方法可为拖轮及拖网渔船等具有自航和拖带两种工况的船舶的动力系统设计提供借鉴。 |

| Abstract:The main engine of a certain harbor tugboat worked under 30% below load during 89% working hours of the tugboat, which led to bad emissions and high fuel consumption. Based on the condition of fixed-pitch rudder propeller, the design of diesel-electric hybrid propulsion system is carried out. The navigation speed of ship model trial and drag force forecast show that this propulsion system could satisfy the technical requirements. The design method of diesel-electric hybrid propulsion system based on fixed-pitch rudder propeller could provide reference for ships which feature working conditions of both self-propulsion and towing, such as tugboats and trawlers. |
