  1. 1. Comparative analysis of contact and non-contact method for determining the natural frequencies of a bolted joint

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Malin Dyberg; Elvira Troillet; [2023]
    Keywords : ;

    Abstract : To ensure high assembly quality of components, a proper clamping force in bolted joints is essential. The existing tightening technology rely on torque and angle; however, this thesis proposes a method for obtaining the clamping force of a bolted joint based on measuring the natural frequencies.

  4. 3. The impact of noice pollution and vibrations on nearby buildings : How is the school Kulturama affected by noise and vibrations from the 'nya tunnelbana' project?

    University essay from KTH/Byggteknik och design

    Author : Hadil Jawad; Aren Nabatyan; [2021]
    Keywords : Noice pollution; vibrations; metro; nya tunnelbana project; noice absorbents; Buller; vibrationer; stomljud; luftburet ljud; nya tunnelbana projekt; absorbenter;

    Abstract : To meet the needs of the growing city of Stockholm, a large-scale project to expand the subway has been initiated. The tunneling involved in the project causes several disturbances, in terms of vibration and noise pollution, on the surroundings. This is problematic as vibration and noise pollution has been shown to have a negative health impact. READ MORE

  5. 4. Estimation of Blocked Forces in an Assembly with Rear Drive Unit as a Source

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srujeeth Khanna Bala; [2021]
    Keywords : Component based TPA; source characterized forces; FEM; Contact forces; ISO20270:2019; Blocked forces; Automotive; NVH; sound and vibration; komponentbaserad TPA; karaktärisering av bullerkällor; FEM; kontaktkrafter; blockerade krafter; bilindustri; ljud och vibrationer; ISO20270:2019;

    Abstract : Experimental validations are widely used for studying dynamic structural behaviors and these studies involve defining the structures completely as being used in real time. While in numerical simulations such detailed features are not specified to ease the computation, thereby deviating from accurate results. READ MORE
