  1. 1. 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

  3. 2. Development of Test Methodology for Electromechanical Linear Actuators

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Isak Linder; [2022]
    Nyckelord :Electromechanical; linear actuator; test methodology; test rig; rack and pinion; transport delay; latency; spring mass damper; load cell; load force; load unit; test unit; DUT; PID; PID control; control mechanics; cogging torque; torque; flex; stiffness; current saturation; torque control;

    Sammanfattning : This master thesis aims to develop a test methodology for electromechanical linear actuators. A linear actuator acts as a linear motor, converting a power source to linear motion. The electromechanical linear actuator in this project has an electric motor as its power source and uses a rack and pinion system to transfer that power to linear motion. LÄS MER

  5. 4. Verification of elastomer characteristics in electro-mechanical linear actuator

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

    Författare :Rohit Karmungikar; [2022]
    Nyckelord :ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

    Sammanfattning : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. LÄS MER

  7. 5. Virtual verification and improvement of innovative wind turbine gearbox design

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

    Författare :Ioannis Pierratos; [2021]
    Nyckelord :Gearbox; Multibody Dynamics; Wind Turbine; Multikroppsdynamik MBS ; Vindkraftverk; Växellåda;

    Sammanfattning : Cascade Drives develops electromechanical linear actuators based on multiple pinions interacting with a gear rack. With a patented load sharing mechanism, that uses flexible torsional elements, the torque is equally distributed among the pinions. LÄS MER
