    Sammanfattning : The vehicle manufacturing sector is constantly evolving, and corporations are fully aware of increased consumer expectations for both driver and passenger´s comfort. SCANIA CV AB, as one of the largest Swedish manufacturers of commercial vehicles, has put an emphasis on this area. LÄS MER

  3. 2. A pre-study of the dynamic behavior of a single diagonal timber arch bridge

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Xiaoqi Wang; Shufan Ye; [2020]
    Nyckelord :: single diagonal arch bridge; timber bridge; footbridge; finite element analysis; resonance induced vibration; bridge dynamics; dimensional analysis;

    Sammanfattning : The aim of this Master’s thesis was to study the dynamic behaviour of a special type ofpedestrian timber bridge with a single diagonal arch - a design proposal made in a previousstudent project. The bridge is intended to be built as a gateway to the Alfred Nobel’s Björkbornin the municipality of Karlskoga. LÄS MER

  4. 3. Train Induced Vibration Analysis of an End-frame Bridge : Numerical Analysis on Sidensjövägen

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Niklas Wiberg; Jasmin Halilovic; [2018]
    Nyckelord :Accelerations; Dynamics; End-frame bridge; FE-modeling; Frequency response function; High-speed railway; Soil structure interaction; Train induced vibrations; 2D 3D;

    Sammanfattning : Higher speeds and higher capacity will cause the Swedish rail network to be exposed to disturbing dynamic effects. Higher speeds cause higher vertical acceleration levels of the bridge deck. In this thesis, a numerical analysis of a three span end-frame bridge subjected to train induced vibrations is performed.

  5. 4. Simulation of Solutions to Excessive Vibration Problems of Pedestrian Footbridges

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :Ezeonwu-Emmanuel Chinedu; Ukoha-Christian Oji; [2008]
    Nyckelord :Dampimg; Modelling; Footbridges; Resonance; ABAQUS; MATLAB.;

    Sammanfattning : Footbriges are often prone to vibrations induced by pedestrian loading. They are long and slender and their weight is moderate. One of the classical and famous examples is the transverse vibrations encountered on the millennium bridge in London. LÄS MER

  7. 5. Study on Vibrations induced by Parametric Excitations on Strings

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :Armando Enrique León Guarena; [2007]
    Nyckelord :Vibrations; Parametric Excitations; Strings; Stay Cables; Modal Analysis;

    Sammanfattning : The present thesis work studies the parametrically excited vibrations on bridge stay cables when the natural frequency of the bridge tower is half of the resonance frequency of the cable. This condition is found at the longest stay cables of the Øresund Bridge. LÄS MER
