  1. 1. Vibration reduction over junctions in buildings

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Alexander Forsberg; Aras Wali; [2021]
    Nyckelord :Vibration reduction; Junction; Building acoustics; Vibrations minskning; Knutpunkt; Byggnadsakustik;

    Sammanfattning : Structure borne sound can travel multiple paths from one office to another and choosing to sound insulate a specific building element can be difficult since all the building elements are connected together and form a coupled system. The current approach by engineers when investigating transmission paths between spaces in a building is using a computer model and assuming that the junctions are firmly clamped or free. LÄS MER

  2. 2. Experimental acceleration Measurements and Finite Elements Modeling

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT); Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Ibrahim Alnimairi; Salim Arrabi; [2021]
    Nyckelord :signal processing. PSD; mode shapes; Mdof; Sdof; PSDT-SVD; finite element modelling;

    Sammanfattning : Heavy crushing machines under their production shifts, creates various levels of vibration, noise and dynamic forces which can be transferred to other parts of the industrial unit. Such kind of factors applies continuous forces on machine parts which can cause gradual fatigue, creep and eventually failure of machine. LÄS MER

  3. 3. HSI effects on pedestrian bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Giancarlo Costa; [2021]
    Nyckelord :Dynamics; HSI; Human Structure Interaction; pedestrian bridge;

    Sammanfattning : The study on Human Structure Interaction (HSI) effects represent a new research field in the design of pedestrian bridges. The presence of pedestrians on the structure affects the dynamic properties of the bridge, and these changes may be quantified in order to design pedestrian bridges in a more efficient way. LÄS MER

  4. 4. 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?

    Kandidat-uppsats, KTH/Byggteknik och design

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

    Sammanfattning : 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. LÄS MER

  5. 5. FE Simulations of Mounting of an Anisotropic Work Piece Material to Reduce the Effects of Vibration

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Punith Prakash; Sudarshan Girigimallayanapalya Shivanna; [2021]
    Nyckelord :Optical cavity; Anisotropy material; FE simulation; Modal analysis.; Technology and Engineering;

    Sammanfattning : Optical cavities should be designed to be insensitive to vibration in all directions. The study of the behavior of the material used to develop an optical cavity is vital for the cavity to be insensitive in all orders. LÄS MER
