【摘要】 张紧器系统是与铺管船配套的关键设备，其动态行为直接影响整个海上铺设作业，目前，铺管船上采用的张紧器装置按照驱动方式可以分为两大类：一类是电动的，一类是液压式的，两者各有其优点，并成熟地应用于各种船舶上。目前，国内对于铺管船用液压式张紧器装置已经有了一些研究，但是对于铺管船用电力拖动张紧器的研究却很少。本文针对张紧器系统工作在恶劣环境的实际情况，应用功率键合图和Matlab／Simulink对电力拖动张紧器系统的动态行为特性进行研究。主要完成了以下几个方面的工作：对张紧器系统的总体设计进行了分析研究，详细的探讨了整个张紧器系统结构、功能和张紧器系统的工作原理。在对张紧器各子系统工作特性研究的基础上，利用键合图建模技术建立了电动机、速度合成器、减速器和履带板等子系统的动态数学模型。同时根据各子系统相互作用关系建立了张紧器系统的动态数学模型。利用张紧器各子系统动态数学模型，建立各子系统的Simulink模块，通过各子系统相互作用关系建立了整个张紧器系统的Simulink模型。在此基础上，完成了张紧器系统的动态仿真，并分别对张紧器系统在无干扰和有干扰的作用下系统的动态响应进行了分析。通过对仿真结果的分析比较，证实了张紧器系统动态模型的有效性。本文成功的实现了电力拖动张紧器系统的动态建模与仿真，其研究成果为指导电力拖动张紧器系统的研制、改进和优化工作奠定了良好的理论基础，具有广泛的应用前景。更多还原

【Abstract】 The tensioner system is a key attachment of pipe laying barge. Its dynamic behavior directly influences the offshore pipe laying operations. So far, there are two types of tensioning equipment used in pipe laying barge: one is the electric driven tensioning system and the other is hydraulic driven tensioning system, each has its advantage, and both of them have been maturely applied in all kinds of pipe laying barges.Recently some research on hydraulic driven tensioning equipment has been made in China, while the study about the electric driven tensioner is rare. This thesis presents the dynamic modeling of electric driven tensioner using power bond graph and Matlab/Simulink technology considering the bitter operation environment of tensioner. The research includes the following contents:The system design of tensioner, which includes system structure, principle of operation, and function of its electric driven system, is discussed deeply.Based on the investigation of characteristic of the subsystems in tensioner system, the dynamic mathematic models of motor, speed synthesizer, reducer and track are developed using power bond graph. Then, according to the coupled relationship of all subsystems, the dynamic mathematic model of tensioner is given.According to the dynamic mathematic models of the subsystems, the Simulink models of the subsystems are developed. Furthermore, the Simulink model of the complete tensioner system is obtained.Then the dynamic behavior with and without disturbance is discussed separately. The aquired simulation results show the feasibility and validity of the tensioner system model.In summery, this thesis succefully realises the complete dynamic modeling and simulation research of electric driven tensioner system.All study results not only play an important theory-instructing role in development, design and optimization of tensioner system, but also have a good future to be applied in practice.更多还原
