【摘要】 随着造船工业以及自动控制技术的发展，调距桨由于比定距桨具有诸多明显的优点而有着广泛的应用。STCW78／95公约(《1978年海员培训、发证和值班标准国际公约(1995年修正)》)已将调距桨船舶动力装置列为高级轮机员的必需培训项目。 基于上述要求，上海海运学院航运仿真中心自行设计开发以调距桨船舶为对象的仿真操纵模拟器。本论文主要内容是研究并建立调距桨船舶推进系统的实时操作仿真模型，并在此基础上设计开发调距桨船舶推进系统操作模拟器仿真软件。 首先，本论文根据船舶推进系统的基本方程，按照物理模型将推进系统分成船-桨、柴油机、螺距控制三个子系统，在此基础上，联系课题主要研究调距桨船舶推进系统的动态性能的实际要求，结合仿真对象的实际情况，分析并实现调距桨螺距液压系统控制模型，对动态性能影响不大的因素，尽量给予简化，以利于模型的建立。 然后，论文结合调距桨船舶的操作系统、报警系统等结构的工作特性、运行原理，利用仿真技术及自动化控制技术，结合仿真对象，分析仿真系统的具体控制与操纵过程，立适用于调距桨船舶推进操纵系统的操纵模型和控制逻辑关系，达到仿真对象的实际操作要求及操作规程。 最后，本论文根据前面建立的数学模型以及系统控制与操纵的要求，基于Windows98操作平台，利用Microsoft公司推出面向Windows的应用程序Visual Basic 5.0作为软件开发工具，结合实际调距桨船舶推进系统的实际组成，设计开发出具有逼真、友好仿真界面，基本达到实时仿真的操作软件。该仿真系统主要由驾驶室操纵台、集控室操纵台、机旁操纵台、CPP液压控制系统、齿轮箱及离合器等组成。 本仿真系统已于2003年9月开发完成，并通过专家组鉴定，认为该系统基本达到了国际海事组织“STCW78／95公约”和我国海事局《海船船员适任考试和评估大纲》对航海类专业学生和高级船员的教学和培训训练的要求。目前，该系统已经在我院以及华东船舶工业学院投入使用。从我院近几期船员培训效果来看，通过对该仿真软件的操作，参加培训的船员对调距桨船舶的基本组成、操作方式、应急控制、螺距调节原理等有了系统的认识，增强了动手能力，达到了预期的培训效果。该系统的研制为我院“SMSC-2000轮机模拟器”功能的延伸和扩展发挥了重要作用，同时为今后调距桨船舶的仿真研究积累了经验。更多还原

【Abstract】 Along with the development of the shipbuilding industry and the automatic control technology, the CPP (controllable pitch propeller) has got the extensive application because of many obvious advantages than FPP (fixed pitch propeller) in ships. STCW78/95 Pact (International Conve- ntion on Standard of Training, Certification and Watchkeeping for Seafares) has listed the propulsion equipment of CPP ships as an essential training item for senior engineer.Because of above-mentioned requirement, The Marine Simulation Center of SMU (Shanghai Maritime University) designed and developed the manipulative simulator according to CPP Ships. The main contents of this thesis are to study and set up real-time operation simulator of CPP ship’s propulsion system, design and develop emulational software for the system.Firstly, according to the basic equationses of ship propulsion system, divided the system into three parts: ship and quant system, diesel engine system and pitch control system with the objective ship, this thesis analyses and realizes the control model of the pitch hydraulic system of CPP ships.Secondly, the thesis combines the working peculiarity and running principle of CPP ships’ operation system & alarm system, utilizes emulation technology and automatic control technologies and establishes control logic relation and simulation model, which used for CPP ships’ propulsion system. This model has reached to operating requiring and operational procedure for objective ship.Lastly, based on Windows 98 as circumstance and Visual Basic 5.0 as tool, the thesis has developed the operation software, which has vivid & friendly emulation interfaces and real-time simulation effects. The system includes bridge control panel, engine room control panel, local control panel, CPP hydraulic control system. Gear-box hydraulic control system and so on.This emulation system has been finished in Sep. of 2003, and approved by specialist group authenticate, which consided the system has achieved the teaching and training require of IMO (International Maritime Organization) STCW78/95 pact for marine students and senior seamans. At present, the system has used at East China Shipbuilding Institute and our academy.Bytraining on the operation system form our academy Training result, seafares can get more Systematic understanding for the CPP system’s components operation mode , emergency control , pitch control principle and have strengthened manipulative ability and reached the anticipated training result. The development of this system has played an important role for extension and expansion of the function of our academy "SMSC-2000 Engine Simulator". At the same time, the research has accumulated experience for the other simulation about CPP for the future.更多还原
