  1. 1. A Topographic Study of Functional Surfaces

    Författare :Robert Ohlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder bore; 3D surface roughness; topography; expert system; AFM; relocation; replication; instrumentation; functional demands;

    Sammanfattning : Surface topography through the years has taken on increased importance, because of the rise in quality demands. The surface often has to meet additional functional demands when products become more complex in accordance with customer preferences. LÄS MER

  2. 2. Wear of piston rings in hydrostatic transmissions

    Författare :Ulf Skytte af Sätra; Sören Andersson; Kenneth Holmberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; piston ring; surface roughness; texture; coating; wear; hydraulic motor; Construction engineering; Konstruktionsteknik; Mechanical engineering; Maskinteknik;

    Sammanfattning : This study focuses on the wear of piston rings in a hydraulic radial piston motor. The piston ring has to satisfy increasing demands for reliability and longer service life. It has two contacting surfaces, the face and the flank, and operates under a boundary lubrication state. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 4. In-Nozzle Flow, Spray and Combustion Investigations of Two-Stroke Marine Diesel Engine Fuel Injectors

    Författare :Reto Balz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray morphology; marine Diesel engine; fuel injection; in-nozzle flow; combustion; cavitation;

    Sammanfattning : This thesis focuses on the experimental studies of the cavitating in-nozzle flow of large two-stroke marine Diesel engine fuel injector nozzles and how it affects the spray morphology and combustion behaviour.  To further increase the efficiency of large two-stroke marine Diesel engines, a better understanding of the fuel spray atomization process is necessary.
