【摘要】 随着生产力的迅速发展和现代化化程度的日益提高，能源的消耗量也急剧增加，导致能源危机和能源价格上涨，使得节能成为当今世界面临的重大技术课题之一。 液体粘性调速离合器是一种靠摩擦片之间的油膜剪切力来传递动力的新型传动方式，在大功率风机、水泵调速节能方面有着广泛的应用前景。 本文研究工作对液体粘性调速离合器的工程应用性和工作特性进行了研究和实验，并解决了产品研制过程中的实际问题。具体内容主要包括以下几个部分： 第一章为绪论，着重分析了选题背景和意义，包括液体粘性调速离合器性能和优势，国内外研究现状。 第二章主要进行了液体粘性调速离合器的设计，包括方案设计、机械结构设计、液压控制系统设计。另外还简述了液体粘性调速离合器几个主要参数的设计理论。 第三章主要为液体粘性调速离合器的油膜受力分析计算。液体粘性调速离合器的动态平衡是摩擦片油膜力综合的结果，决定了液体粘性调速离合器的静态性能和动态性能，是系统理论分析的基础。 第四章以第三章油膜受力分析为基础，建立了液体粘性调速离合器的动态数学微分方程和增量传递函数，为具体分析液体粘性调速离合器的动态性能，以及针对液体粘性调速离合器的工作性能进行了控制器算法的选择。 第五章在理论分析的基础上，利用仿真软件对液体粘性调速离合器的静、动态性能进行了仿真分析和研究，验证了液体粘性调速离合器理论的正确性。 第六章对全文的研究工作讲行了简要总结和今后工作的展望。更多还原

【Abstract】 With the rapid development of productivity and the increasing promotion of modernization, the consumption of energy is being greatly increased, which may lead to energy crisis or the rising of the price of energy. As a result, the target of energy saving has been a more and more emergent task.As a new type of power transmission device utilizing the shear of oil of film between two sets of discs. It is widely used for speed regulation and energy saving in large fans and pumps.This thesis introduce the research and experiment of the application and the characteristic of the hydro-viscous drive, as well as problem solving in development of the hydro-viscous drive in practice. It focuses on the static performance and dynamic performance of the hydro-viscous.Chapter 1 mainly introduces the background and significance of the research theme, including the performance of the hydro-viscous and the advantage of the use of hydro-viscous. It also introduce of the development of the hydro-viscous at home and abroad.In chapter 2, the design of hydro-viscous will be the theme, ranging from the project design to mechanical design and hydraulic control system design. It also introduces several parameter designs in hydro-viscous drive.Chapter 3 is mainly about the analysis and calculation of the force acted on the surface of the oil film between two sets of the discs in hydro-viscous system. The dynamic balance is compositive result of the forces, which play a great importance on the static performance and dynamic performance of the hydro-viscous. It is the basis of the theory analysis of the research.Chapter 4 studies the dynamic model of the hydro-viscous by drawing its transmission functions and flow continuation equation based on the its dynamic force balance. The study of this chapter offers theoretical foundation and direction for next step study.In chapter 5, based on theoretical analysis of the hydro-viscous dynamic performance, digital simulation is done by using general dynamic simulation softwareMatlab. The experiment is also operated to validate the legitimacy of the theoretical analysis.Chapter 6 is the summary of the paper’s study work and the prospect of the next step’s work.更多还原
