  1. 21. Ride Quality and Drivability of a Typical Passenger Car subject to Engine/Driveline and Road Non-uniformities Excitations

    Master-uppsats, Fordonssystem

    Författare :Neda Nickmehr; [2011]
    Nyckelord :Ride quality; Driveline; Engine excitations; Road non-uniformities; Suspension System; Torsional vibration; Random process;

    Sammanfattning : The aim of this work is to evaluate ride quality of a typical passenger car. This requires both identifying the excitation resources, which result to undesired noise inside the vehicle, and studying human reaction t applied vibration. LÄS MER

  3. 22. Detection of mobile phone vibrations during walking

    Master-uppsats, Lunds universitet/Kognitionsvetenskap

    Författare :Max Martinsson; [2011]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Today the use of mobile phones are widespread, and they are often kept in trouser pockets. As the thigh is comparatively less sensitive to vibrations, and vibrotactile sensitivity is diminished during movement, detection of vibratory mobile notications during walking is lower than in a still position.

  4. 23. Sound and Vibration Measurements of Metal Plates

    Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Forooz Shahbazi; [2009]
    Nyckelord :sound and vibration measurements; Metal Plates;

    Sammanfattning : Abstract The purpose in this project is to classify different metal plates according to their size and material. The plates which are studied are small plates with the maximum size of: radius=25.75 mm and thickness=2.20 mm. LÄS MER

  5. 24. Correlation of Sinusoidal Sweep Test to Field Random Vibrations

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :Praveen Gurindapalli; Jaya Hari Lade; [2005]
    Nyckelord :FDS; Equivalence; Sinusoidal Sweep; PSD; MIL-STD 810F; IEC-STD; and MATLAB.;

    Sammanfattning : The vibration load subjected to many products is the combination of several random processes corresponding to different application conditions, such as the various field road load inputs for automotive components. Sometimes the input loads are the combination of random and sinusoidal vibration. LÄS MER

  7. 25. Analysis of Body Kinematics and Force Modulation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Magnus Hjerpe; [2001]
    Nyckelord :Technology and Engineering;

    Sammanfattning : To analyse the connection between kinematics and stabilizing forces related to human postural dynamics, fourteen normal subjects were investigated with posturography. Stimulation signals according to Pseudo-Random- Binary-Sequence patterns were applied to each subject. LÄS MER
