  1. 1. 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

  3. 2. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

    University essay from KTH/Betongbyggnad

    Author : Viktor Peterson; Zihao Wang; [2020]
    Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2- method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings iv;

    Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be foundin Groningen, the Netherlands. More and more induced earthquakes with shortduration have been detected in this region due to gas exploitation. READ MORE

  5. 4. Height Determination of the Acceleration Region for Dayside Occurring Auroral Arcs

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Sandström; [2014]
    Keywords : ;

    Abstract : The aim for this bachelor thesis is to determine the altitude of the auroral acceleration region occuring on the dayside. Substantial work has already been done on this topic, but for occurrence at the nightside. In this paper only negative quasi-static potential structures were considered, as they are the main contributor for producing aurora. READ MORE

  6. 5. Fuel Consumption Tuning for Electric All Wheel Drive System

    University essay from Signaler och System

    Author : Richard Hallvig; [2013]
    Keywords : Bränsleekonomi; hybridbilar;

    Abstract : This report investigates methods to reduce fuel consumption in SAAB's prototype hybrid car. It is primarily concerned with changes in the final drive ratio (FDR) of the gearbox. Reducing the FDR lowers the engine speed, allowing the engine to run at a more efficient operating point. READ MORE
