  1. 1. Design of a stabilizer for the Slotborer

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Oliver Wigardt; [2018]
    Keywords : Slotborer; Mass damper; stabilizer; adjustable tuned mass damper; Slotborer; mass dämpare; stabilisator; justerbar massdämpare;

    Abstract : Platinautvinning är antagligen en av the farligaste gruvindustrierna. På följd av det har gruvmaskiner som Slotborer utvecklats för att göra utvinningsprocessen säkrare. Slotborern är ett ganska nytt koncept och har problem med vibrationer i borrsträngen när den blir längre. READ MORE

  3. 2. The potential of Fluid Dynamic Absorbers for railway vehicle suspensions

    University essay from KTH/Spårfordon

    Author : Visakh V Krishna; [2016]
    Keywords : ;

    Abstract : The main running objectives concerning the vertical dynamics of passenger rail vehicles are ride comfort and safety. The goal of this thesis is to employ the use of a Fluid Dynamic Absorber to minimize the vertical acceleration of the car body while minimizing the dy-namic force fluctuations in the wheel rail contact.

  4. 3. Dynamic Analysis of Long Span Footbridges

    University essay from KTH/Bro- och stålbyggnad

    Author : YINA FAN; FANGZHOU LIU; [2015]
    Keywords : footbridge; pedestrian-induced vibration; Sétra; Eurocode; vertical acceleration;

    Abstract : A footbridge in Slussen is planned to be built and will connect the area of Gamla Stan with Sodermalm. As an increasing number of footbridges with large span tend to become more flexible and light these days, the corresponding dynamic problems due to decreased stiffness and mass draw much more attention.

  5. 4. Vibration Control of a High-Speed Railway Bridge Using Multiple Tuned Mass Dampers

    University essay from KTH/Bro- och stålbyggnad

    Author : Heydar Beygi; [2015]
    Keywords : Tuned mass dampers; Dynamic analysis; high-speed railway bridge; Banafjäl bridge;

    Abstract : In the current thesis, the Banafjäl Bridge located on the Bothnia line (Botniabanan) in northern Sweden was studied. The bridge is a 40m long composite ballasted high-speed railway bridge. A 3D FE model of the bridge was developed using a commercial FE software, Abaqus. The FE model was calibrated against the measured data of the bridge. READ MORE

  6. 5. Experimental Characterization of Fixtures Design: A comprehensive study on vibration minimization technique by using viscoelastic materials

    University essay from KTH/Industriell produktion

    Author : Md Zamiul Mottasim; [2014]
    Keywords : ;

    Abstract : Damping is a phenomenon which is obviously related with dissipation of vibration energy under relative motion in a mechanical system. Without changing excitation force in many cases vibration is reduced only by changing mass or stiffness of the system just with altering the resonance frequencies. READ MORE
