  1. 1. Gearbox noise : Correlation with transmission error and influence of bearing preload

    Författare :Mats Åkerblom; Sören Andersson; D. Houser; KTH; []
    Nyckelord :gear; gearbox; noise; vibration; transmission error; bearing preload; Mechanical engineering; Maskinteknik;

    Sammanfattning : The five appended papers all deal with gearbox noise and vibration. The first paper presents a review of previously published literature on gearbox noise and vibration. The second paper describes a test rig that was specially designed and built for noise testing of gears. LÄS MER

  3. 2. Error analysis of summation-by-parts formulations : Dispersion, transmission and accuracy

    Författare :Viktor Linders; Jan Nordström; Marco Kupiainen; Mark Carpenter; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis we consider errors arising from finite difference operators on summation-by-parts (SBP) form, used in the discretisation of partial differential equations. The SBP operators are augmented with simultaneous-approximation-terms (SATs) to weakly impose boundary conditions. LÄS MER

  4. 3. Modelling and Simulation of Gearset Behavior : Effects of Manufacturing Errors and Electrification

    Författare :Rikard Hjelm; Maskinelement; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrification; gears; LTCA; tip contact; pitch error; profile slope error; transmission error; tolerance; scrapping; lubrication; TEHL; optimization;

    Sammanfattning : Due to electrification, new demands are imposed on gears regarding e.g., quality, noise, lubrication, and gear ratio.Therefore, a better understanding of gearset meshing and operation is needed. LÄS MER

  5. 4. Internet Video Transmission

    Författare :György Dan; Gunnar Karlsson; Viktória Fodor; Jean-Yves Le Boudec; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic control; MDC; FEC; Multicast streaming; Queuing theory; Telecommunication; Telekommunikation;

    Sammanfattning : The Internet has rapidly evolved from being a scientific experiment to a commercial network connecting millions of hosts that carries traffic generated by a large amount of applications with diverse requirements. Its architecture was however designed to enable efficient point-to-point delivery of bulk data, and can not provide statistical guarantees on the timely delivery of delay sensitive data such as streaming and real-time multimedia.

  7. 5. Low Frequency Impact Sound in Timber Buildings : Transmission Measurements and Simulations

    Författare :Jörgen Olsson; Andreas Linderholt; Börje Nilsson; Carl Hopkins; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timber floors; FE-simulations; Light weight floors; Frequency response functions; Building acoustics; Byggteknik; Civil engineering;

    Sammanfattning : An increased share of multi-story buildings that have timber structures entails potential in terms of increased sustainability as well as human-friendly manufacturing and habitation. Timber buildings taller than two stories were prohibited in Europe until the 1990s due to fire regulations. In 1994, this prohibition was removed in Sweden. LÄS MER
