【摘要】：用于海上吊装作业的起重机是一种重要的海洋工程装备,其作业安全性与可靠性历来受到各方高度关注。在众多威胁吊装安全的因素中,海浪起伏使吊装货物受到的不可控运动(特别是升沉运动)对起重机吊装作业安全危害极大。因此,用以解决该问题的升沉补偿技术已经成为海工装备制造业的核心技术之一。本文对绞车式主动升沉补偿系统相关技术进行深入研究,在已有研究的基础上进行了系统设计,将泵控液压马达技术、能量回收技术与液压二次调节技术结合起来,再加上差动减速器对主起升与补偿运动的合成,形成了一种新型绞车式主动升沉补偿系统。本文对该系统进行了原理设计、主要系统参数设计计算以及重要部件的详细设计,建立了对应系统的AMESim计算机仿真模型并实施了对系统工作性能的仿真分析,结果表明所设计的系统参数准确,控制性能符合实际要求,在原理上具有可行性。在初步设计的基础上,本文又对系统进行了优化设计,主要优化对象为泵控液压马达系统与PID控制器。在此过程中,系统参数与控制性能进一步得到优化,并在优化设计参数的基础上实施了第二次仿真分析。仿真结果可以看出,系统整体工作性能有较好的提高,达到了优化的目的。为了下一步研制工作的顺利进行,在此对系统实验方案进行了初步设计。
[Abstract]:For offshore hoisting crane is a kind of important marine engineering equipment, the operation safety and reliability has always been highly concerned. Among the many factors threatening the safety of lifting, lifting the waves is not controllable by sports goods (especially the heave) of crane lifting safety hazards greatly. Therefore, already industrial equipment manufacturing industry has become one of the core technology to solve the problem of sea heavecompensation technology. The winch type active heave compensation system or related technology research, design of the system on the basis of the previous research, the pump controlled hydraulic motor and hydraulic energy recovery technology, technical regulation technology combined with two times together, plus the differential decelerator synthesis of main hoisting and motion compensation, the formation of a new type of winch type active heave compensation system. The system of the original Design, detailed design of the main system parameters and key components, established the AMESim simulation model of the corresponding system and carry out simulation analysis on the system performance, the results show that the system design parameter accurately, control performance meets the actual requirements, it is feasible in principle. Based on the preliminary design of this paper. And optimize the design of the system, the main object of optimization for hydraulic pump controlled motor system with PID controller. In this process, the system parameters and the control performance is further optimized, and the implementation of the analysis of the second simulation based on optimal design parameters. Simulation results show that the system has better overall performance improvement in order to achieve the purpose of optimization. The next step of the research work carried out smoothly, the preliminary design of the system of experimental program.
