  1. 11. Energy Management of Parallel Hydraulic Hybrid Wheel Loader

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hoang Thai Do; [2018]
    Nyckelord :;

    Sammanfattning : Hybridization of driveline system is one possible solution to increase fuel eciency.In this thesis a parallel hybrid hydraulic wheel loader concept was studied. A highpressure accumulator was added to the system and acted as a second source of energy. LÄS MER

  3. 12. Large Eddy Simulation of Turbulent Flow over a Backward-Facing Step

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Edmond Shehadi; [2018]
    Nyckelord :;

    Sammanfattning : This work studies the effect of grid resolution and subgrid scale modeling on the predictive accuracy of Large Eddy Simulation. In particular, the problems considered are: turbulent flow over a backward-facing step and fully-developed turbulent channel flow. LÄS MER

  4. 13. Fast Real-Time MPC for Fighter Aircraft

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Amanda Andersson; Elin Näsholm; [2018]
    Nyckelord :MPC; fast MPC; explicit MPC; fighter; aircraft; neural network; model predictive control; interior-point method;

    Sammanfattning : The main topic of this thesis is model predictive control (MPC) of an unstable fighter aircraft. When flying it is important to be able to reach, but not exceed the aircraft limitations and to consider the physical boundaries on the control signals. LÄS MER

  5. 14. Simulation of cantilever construction of cable-stayed bridges taking into account time dependent phenomena

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Josep Farre Checa; [2017]
    Nyckelord :Cable-stayed bridges; Cantilever method; Objective Service Stage; CIP concrete; Creep; Dischinger hypothesis; Forward analysis.;

    Sammanfattning : In the design of cable-stayed bridges, the construction analysis is very important since the worst stresses are usually reached during the construction process. In addition, if the bridge is made of concrete, the effects of time dependent phenomena have great importance. LÄS MER

  7. 15. FE-Modelling and Material Characterization of Ice-Hockey Helmet

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Isotta Rigoni; [2017]
    Nyckelord :traumatic brain injury; ice-hockey; helmet; finite element;

    Sammanfattning : The aim of this research was to produce a reliable finite element model of a helmet, that could be used to simulate approval tests as well as impacts to investigate the safety offered. A 2D and 3D mesh was generated from the CAD file of an Easton Synergy 380 with HyperWorks, and then checked referring to standard parameter values. LÄS MER
