  1. 1. Drop-weight impact tests on reinforced concrete beams

    University essay from KTH/Betongbyggnad

    Author : John Abdalnour; Milad Saliba; [2023]
    Keywords : ;

    Abstract : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. READ MORE

  3. 2. Dynamic Analysis of Portal Frame Bridges for High-Speed Trains : A Parametric Study

    University essay from KTH/Bro- och stålbyggnad

    Author : Antonio Dib; Ramayana Salgado; [2023]
    Keywords : ;

    Abstract : A high-speed railway network is important for Sweden’s development. However, anincreasing train speed brings new challenges in bridge design due to higher bridgeaccelerations. READ MORE

  4. 3. Design, Modeling, and Testing of a Force Feedback Haptic Device for Simulated Robot Interaction

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Patrik Lindström; [2023]
    Keywords : Force Feedback; Impedance Control; PD-gain; Dynamic Behavior; Closed-chain; Master-Slave; Parallel Manipulator; Kinematics Redundancy; Mass-Spring-Damper; Position Control; Current Control; Modeling; Design; Joints; Delta robot; Differential Equations; External Torques; Kinematics; Forward Kinematics; Inverse Kinematics; Dynamic Matrices; Jacobian; URDF; Haptics; Haptic Device; Solidworks; CAD; Maxon Motors; EtherCAT; Beckhoff;

    Abstract : Haptic feedback is a growing phenomenon that incorporates the sense of touch through tactile sensations such as vibrations, electrical signals, air pressure, and sound waves or through force feedback, which employs torques and/or forces to replicate the pressure and weight of a simulated object. Utilizing haptic technology establishes a communication bridge between the user and the technical component, enhancing the user's understanding of the technical component's surroundings. READ MORE

  5. 4. Analysis of Footbridge Comfort Vibrations

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Niklas Thuresson; Henrik Ruuth; [2023]
    Keywords : footbridges; dynamics; vibrations; accelerations; Sétra; comfort vibrations; natural frequencies; Technology and Engineering;

    Abstract : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. READ MORE

  6. 5. A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations

    University essay from KTH/Bro- och stålbyggnad

    Author : ALEJANDRO GARCÍA GARCÍA; [2022]
    Keywords : Arch bridges; footbridge dynamics; critical load; bridge typology; parametric study;

    Abstract : The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously evaluating the dynamic and static performance of timber arch footbridges.
