  1. 1. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  3. 2. Loading tests on composite concrete columns : A comparison between composite columns made of permanent 3DPC formwork filled with SCC and columns made of homogenous SCC

    Master-uppsats, KTH/Betongbyggnad

    Författare :Abdulla Al-Bazarkan; Hussain Alahmad; [2023]
    Nyckelord :;

    Sammanfattning : In order to achieve increased sustainability when casting concrete structures this thesis investigates the possibility of utilizing 3D-printing to construct formwork and digitalize construction. By digitizing construction less workers are needed and therefore less capital. LÄS MER

  4. 3. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  5. 4. Real time control of an active pendulum arm suspension system for a downscaled XT28 forwarder model

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Niclas Määttä; Adam Westermark; [2023]
    Nyckelord :mechatronics; offset-free MPC; MPC; LQR; XT28; forwarder; pendulum arm; forestry; mekatronik; offset-free MPC; MPC; LQR; XT28; skotare; pendelarm; skogsbruk;

    Sammanfattning : A forwarder named XT28 has been developed in joint collaboration between eXtractor AB, Skogforsk AB, KTH, Linköpings Unversity, Sveaskog, and Bosch Rexroth. The forwarder is equipped with six hydraulic active suspension pendulum arms. LÄS MER

  7. 5. Electrification Of A Tiltrotator : Electrifying The Hydraulic Tilt Function

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Viggo Jonason; [2023]
    Nyckelord :Electrification; Hydraulic systems; Efficiency; Electromechanical Actuators; Tiltrotator.; Elektrifiering; Hydrauliska system; Verkningsgrad; Elektromekaniska aktuatorer; Tiltrotator.;

    Sammanfattning : As new emission regulations in the EU set more stringent requirements on greenhouse gas (GHG) emissions, original equipment manufacturers (OEM) must find ways to align with the EUs sustainability goals. By transitioning to more electrically driven machinery, operators of off-highway vehicles can benefit from better fuel economy, lower greenhouse gas emissions and less air pollution. LÄS MER
