  2. 1. A mechanical model of an axial piston machine

    Author : Rasmus Löfstrand Grip; Ulf Sellgren; Niclas Strömberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-body mechanical model; axial piston; Z-shaft; wobble plate; Sophia; Engineering mechanics; Teknisk mekanik;

    Abstract : A mechanical model of an axial piston-type machine with a so-called wobble plate and Z-shaft mechanism is presented. The overall aim is to design and construct an oil-free piston expander demonstrator as a first step to realizing an advanced and compact small-scale steam engine system. READ MORE

  4. 2. Suction dynamics of axial piston pumps

    Author : Pär-Erik Wiklund; KTH; []
    Keywords : ;

    Abstract : Computational fluid dynamics (CFD), extensive experimentalstudies and a one-dimensional model based on two pressurereduction coefficients are used in this thesis to analyse thesuction dynamics of an bent axis axial piston pump. Specialattention is given to cavitation since a great deal of problemsare related to this very important phenomenon. READ MORE

  5. 3. Design principles for noise reduction in hydraulic piston pumps : simulation, optimisation and experimental verification

    Author : Andreas Johansson; Kevin Edge; Linköpings universitet; []
    Keywords : hydraulic piston pumps; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Noise reduction in hydmulic systems has been an important research topic for several decades. In recent years, industry's interest in the area has grown dramatically. The reason is new national and international requirements and legislation governing working conditions. READ MORE

  6. 4. A Low-Leakage Linear Transverse-Flux Machine for a Free-Piston Generator

    Author : Waqas Arshad; KTH; []
    Keywords : Free-piston generators; linear machines; transverse-flux machines; hybrid vehicles; electrical machines design;

    Abstract : The presented work is about a new low-leakage lineartransverse-flux electrical machine.The machine is dimensionedfor a free-piston generator. The intended application is inseries-hybrid vehicles. The free-piston generator is anintegration of a free-piston combustion engine with a linearelectrical machine. READ MORE

  7. 5. Performance analysis of a low-speed high-torque hydrostatic transmission unit

    Author : Håkan Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : This thesis concerns a study of the performance of an industrial low-speed high-torque hydrostatic drive system. This type of hydrostatic transmission is commonly used in continuous operation in a wide range of heavy-duty drive applications. In many applications the transmissions have to compete with e.g. READ MORE
