  1. 1. HSI effects on pedestrian bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Giancarlo Costa; [2021]
    Keywords : Dynamics; HSI; Human Structure Interaction; pedestrian bridge;

    Abstract : 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.

    Keywords : Wind Turbine; Offshore; Blade; Rotor; Computational Fluid Dynamics; Airfoil; Aerodynamic; Aeroelasticity; Simulation; Fluid; Structure; Interaction; Loads; Control; Response; Harmonics; Vibration; Damping; Flutter; Trailing Edge; Flaps; Wind Gust; Lift; Drag; Unsteady; Pressure; Velocity; Vindkraftverk; offshore; blad; rotor; beräkningsvätske-dynamik; flygplatta; aerodynamisk; aeroelasticitet; simulering; vätska; struktur; interaktion; belastningar; kontroll; respons; övertoner; vibrationer; dämpning; fladdring; bakkant; klaffar; vindstöt; lyft; Drag; ostadig; tryck; hastighet;

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

  3. 3. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation

    University essay from KTH/Bro- och stålbyggnad

    Author : Sicong Wei; [2020]
    Keywords : high-speed railway; nonlinear dynamics; bridge bearings; friction; hysteresis; secondary development; damping;

    Abstract : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. READ MORE

  4. 4. Vehicle Integration between Carl-Gustaf M4 and Trackfire RWS : A concept study on mechanical solutions

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Isabelle Dietmann; [2020]
    Keywords : Carl-Gustaf; Trackfire; Recoilless Rifle; Remote Weapon Station; Concept Study; Saab Dynamics;

    Abstract : Saab Dynamics is a division of Swedish company Saab AB, offering solutions, products, and services for military defence. Included in the Saab Dynamics portfolio is the Carl-Gustaf recoilless rifle; a man-portable, reusable, anti-tank weapon system. READ MORE

  5. 5. Response of Footbridges equipped with TLD : A numerical and experimental assessment

    University essay from KTH/Bro- och stålbyggnad

    Author : Silhady Tshitende Luboya; [2020]
    Keywords : Tuned liquid damper; tuned mass damper; dynamic analysis; dynamics evaluation; vibration; footbridge; human-induced vibrations; parametric study; serviceability; assessment.;

    Abstract : In recent years, an increase to design slender and aesthetically-pleasing structures have resulted in some structures having a low natural frequency. This is because the design calculation did not meet the requirement of serviceability performance. READ MORE
