  1. 1. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön

    University essay from KTH/Spårfordon

    Author : Ngoc Thúy Vy Dang; [2021]
    Keywords : rail defects; rail reliability; Ultrasonic Test; wheel damage; Wheel Impact Load Detector; statistics; järnvägsdefekter; järnvägssäkerhet; ultraljudstest; hjulskador; hjullastningsdetektor; statistik;

    Abstract : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. READ MORE

  3. 2. Efficiency verification of an electromechanical linear actuator

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ingela Råberg; [2021]
    Keywords : Efficiency; Linear actuator; Modelling; Romax; Linjärt ställdon; Modellering; Romax; Verkningsgrad;

    Abstract : Cascade Drives has developed an electromechanical linear actuator with a patented feature which allows for load sharing between multiple pinions interacting on the same rack. This arrangement has proven resilient for shock loads, and allows for compact gearbox designs with very high load rating. READ MORE

  4. 3. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

    University essay from KTH/Lättkonstruktioner

    Author : Carl Järmyr Eriksson; [2021]
    Keywords : Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

    Abstract : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. READ MORE

  5. 4. Comparative study of the static and quasi-static compliance measurement procedures on industrial manipulators

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Katrin Kersch; Anwar Ahmad Rana; [2021]
    Keywords : industrial manipulators; stiffness; compliance calibration; pose accuracy; Industriella manipulatorer; stelhet; efterlevnadskalibrering; positionsnoggranhet;

    Abstract : Serial articulated industrial manipulators are increasingly used in machining applications due to their flexibility in application and their cost-effectiveness compared to conventional machinery. However, the use of industrial manipulators in machining processes that subject the robot to high loads such as in drilling is limited. READ MORE

  6. 5. Shock Load Absorption of Electro-mechanical Actuators

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kenan Güler; Milan Andelkovic; [2021]
    Keywords : Shock loads; electro-mechanical actuators; load absorption; Stötbelastningar; elektro-mekaniska ställdon; dämpningsförmåga;

    Abstract : När ett ställdon får som krav att kunna överföra höga krafter i relativt höga hastigheter med en dessutom väldigt hög precision är elektromekaniska ställdon oftast att föredra. En traditionell pinjong-kuggstång-uppställning uppfyller vissa av de kraven, men om kraften ska ökas behövs det fler än ett pinjongpar. READ MORE
