【摘要】 蒸汽动力系统是船舶动力装置的应用形式之一，在大型或超大型远洋船舶中，蒸汽动力装置的应用依然很广泛。锅炉是船舶蒸汽动力装置中的主要设备，它被喻为船舶的心脏。增压锅炉装置具有尺寸小、重量轻、机动性好等特点，是船舶蒸汽动力系统的发展方向。增压锅炉装置性能的优劣影响船舶的运动性能，还影响以增压锅炉为能量来源的设备。目前，还没有建立完整的用于研究增压锅炉与涡轮增压机组在动态条件下的匹配特性，以及增压锅炉装置在船舶变负荷运行过程中响应特性的仿真模型。本文以某船舶增压锅炉装置为研究对象，基于传热学和流体力学基本理论，以GSE系统仿真工具为依托，利用JTopmeret两相流图形化建模软件和Fortran编程语言建立了船用增压锅炉系统仿真模型，对仿真模型进行稳态仿真试验得到了不同工况系统主要参数的仿真值，通过设计值与仿真值的比对，验证了模型的精确性；通过动态特性仿真试验得到了阶跃扰动条件下增压锅炉装置的响应曲线，以及船舶在加速过程中增压锅炉系统的响应特性；对动态结果进行分析，曲线变化趋势符合物理对象的过程机理与基本规律。本文建立的仿真模型可以为后续船舶蒸汽动力系统的故障仿真打下良好基础，通过完善仿真模型以及进一步提高模型精度，可用于培训运行操作人员；动态响应结果分析可为增压锅炉装置的设计及控制策略的优化提供理论依据。更多还原

【Abstract】 Steam power systems is one of the application forms of marine power plant. Steampower system is widely used for large ocean ships. The boiler is the main equipment ofmarine steam power system, it has been called the heart of the ship. Supercharged boiler unithas a good prospect due to its small size, light weight, good flexibility. The performance ofsupercharged boiler unit will affect the mobility of the ship power plant, and also affect theenergy supply demand, which depends on supercharged boiler. By now, there is still nosimulation model for research of the matching performance of supercharged boiler andturbocharged set in dynamic conditions.This thesis takes the a type of supercharged boiler as object of research based on the heattransfer and fluid mechanics principle. A simulation model for researching of the matchingperformance of supercharged boiler unit by JTopmeret and Fortran software. The accuracy ofmodel has been verified through comparison of the simulation value and the designed value.A step disturbance was made in the dynamic conditions in order to get the response curve ofsupercharged boiler unit, and the research on dynamic response of supercharged boiler unitaccompanied by the ship’s speed increase was also made. The change trend of the responsecurve adjust to the process mechanism and the basic law.The simulation model can be used for the further research on the marine steam powersystem fault simulation. It can be used for training the operators through perfecting the visualinterface and improving the model accuracy. The analysis of dynamic response curve cansupply the design and control principle of supercharged boiler unit theoretical basis.更多还原
