    Sammanfattning : Powertrain mounts' purpose is to mount the engine and the gearbox in the car. Besides that, it isolate the body from the powertrain movements and road excitation. The most common material in powertrain mounts bracket is aluminum but lately, fibre reinforced polymer (FRP) has been acting as a substitute for the aluminum. LÄS MER

  4. 13. Torsional Stiffness Calculation of CFRP Hybrid Chassis using Finite Element Method : Development of calculation methodology of Formula Student CFRP Chassis

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Nyckelord :;

    Sammanfattning : There has been a considerable increase in the usage of paper products due to its sustainability in the product cycle. Many environmental and process variables can affect the mechanical behavior of paper from its making to finished products. LÄS MER

  7. 15. FEM modelling of sound reduction index in partition CLT wall

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Teknisk akustik

    Författare :Adam Hultin; Erik Hörström; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Constructing buildings with wood brings many advantages, especially regarding environmental aspects, which has brought an up-rise in these types of structures. However, one of the main issues regarding wooden structures is its tendency to perform poorly acoustically in lower frequencies compared to heavier structures. LÄS MER
