  3. 3. Development of a Method to Determine the Influence of Rubber Components in Dynamic Simulations

    Master-uppsats, KTH/Farkostteknik och Solidmekanik

    Författare :Mårten Vuorinen; [2022]
    Nyckelord :;

    Sammanfattning : In order to make sure that an engine can withstand the vibration loads, while the weight is kept as low as possible, some components on the engine are made of rubber. The stiffness of these rubber components are several orders of magnitude lower than the surrounding metal components, and the inclusion of rubber components affects the dynamic behaviour of the engine.

  4. 4. NVH analysis and optimization of electric powertrain

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Anujit Dafle; [2022]
    Nyckelord :Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

    Sammanfattning : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. LÄS MER

  5. 5. Numerical study of a vibroacoustic wave trap for e-vehicles

    Master-uppsats, KTH/Teknisk akustik
