  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

  4. 4. Development and Application of Reactor Noise Diagnostics

    Författare :Joakim K.-H. Karlsson; Chalmers University of Technology; []
    Nyckelord :BWR stability; noise decomposition; reactor noise; control rod vibrations; core barrel vibration; density wave oscillations; noise diagnostics; PWR noise; localisation; channel instability;

    Sammanfattning : A number of problems in reactor noise diagnostics have been investigated within the framework of the present thesis. The six papers presented cover three relatively different areas, namely the use of analytical calculations of the neutron noise in simple reactor models, some aspects of boiling water reactor (BWR) stability and diagnostics of core barrel motion in pressurized water reactors (PWRs).

  5. 5. Environmental Impact from Wave Energy Converters : Underwater Noise

    Författare :Kalle Haikonen; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Wave energy conversion is a potentially clean and sustainable form ofenergy conversion with no emissions of gases or liquids during operation.There are other environmental issues that need to be taken in consideration.The deployment of a wave power farm will contribute with new surface formarine organisms to colonize.
