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

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

    Abstract : 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. READ MORE

  3. 3. Gear Surface Machining for Noise Suppression

    Author : Naser Amini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gear grinding; gear shaving; gears; undulation; surface topography; noise; automotive gearboxes; ghost harmonics; gear honing;

    Abstract : Gear noise in modern automobiles is unacceptable. It has different sources, such as design parameters and manufacturing errors. Manufacturing errors, for example, can be reduced using advanced grinding operations. However, sometimes grinding operations can introduce micro-geometry deviations that cause severe noise problems.

  4. 4. Final Approach : Measurements and Ratings of Aircraft Landing Noise

    Author : Anders Johansson; Karl Bolin; Susann Boij; Antonio Filippone; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft noise; acoustic measurements; psycho acoustics measurements; noise annoyance; Flygplansbuller; akustiska mätningar; psykoakustiska mätningar; bullerstörning; Teknisk mekanik; Engineering Mechanics;

    Abstract : Följande avregleringen av flygmarknaden har flygtrafiken ökat snabbt sedan mitten av 1990-talet. Detta har oundvikligen lett till en utbyggnad av flygplatser, vilket på många platser runt om i världen har lett till oro och konflikter på grund av ökade bullernivåer. READ MORE

  5. 5. Gear engagement control for transmissions in hybrid electric vehicles

    Author : Muddassar Piracha; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Noise and wear minimization; Dog Clutch; Hybrid Powertrain; Optimal control; LQI control; Mechanical Synchronizers; Dedicated Hybrid Transmission; Gear shifting; Drivability; Dual Clutch Transmission; Electric Powertrain; Phase plane analysis;

    Abstract : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. READ MORE
