  1. 6. Investigation of Mode Superposition as Modelling Approach for Crankshaft Torsion

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jonas Johansson; [2018]
    Keywords : Torsion; Crankshaft; Modal analysis; Mode superposition;

    Abstract : With tougher emission standards for heavy duty trucks, good control of the engine is of importance. By taking into consideration the torsional vibrations occurring in the crankshaft, the engine control can be improved. READ MORE

  3. 7. Modal analysis of pedestrian-induced torsional vibrations based on validated FE models

    University essay from KTH/Bro- och stålbyggnad

    Author : Simon Chamoun; Marwan Trabulsi; [2017]
    Keywords : Modal analysis; validated FE models; pedestrian-induced vibrations;

    Abstract : Finite element (FE) models serve as the base of many different types of analysis as e.g. dynamic analysis. Hence, obtaining FE models that represent the actual behaviour of real structures with great accuracy is of great importance. READ MORE

  4. 8. Modeling and Control of a Parallel HEV Powertrain with Focus on the Clutch

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Mahdi Morsali; [2015]
    Keywords : parallel hybrid electric vehicles; clutch modeling; driveline modeling; torsional vibrations; slipping clutch; energy management; optimization;

    Abstract : Nowadays, the increasing amount of greenhouse gases and diminishing of the existing petroleum minerals for future generations, has led the automotive companies to think of producing vehicles with less emissions and fuel consumption. For this purpose, Hybrid Electric Vehicles (HEVs) have emerged in the recent decades. READ MORE

  5. 9. Development and Evaluation of Model-Based Misfire Detection Algorithm

    University essay from Linköpings universitet/Fordonssystem

    Author : Linus Therén; [2014]
    Keywords : Model-Based; Misfire; Detection; Diagnosis; Kullback-Leibler; SVM;

    Abstract : This report present the work to develop a misfire detection algorithm for onboard diagnostics on a spark ignited combustion engine. The work is based on a previous developed model-based detection algorithm, created to meet more stringent future legislation and reduce the cost of calibration. READ MORE

  6. 10. LQG-control of a Vertical Axis Wind Turbine with Focus on Torsional Vibrations

    University essay from Avdelningen för systemteknik

    Author : Adam Alverbäck; [2012]
    Keywords : LQG-control; Vertical axis wind turbine; torsional oscillations;

    Abstract : In this thesis it has been investigated if LQG control could be used to mitigate torsional oscillations in a variable speed, fixed pitch wind turbine. The wind turbine is a vertical axis wind turbine with a 40 m tall axis that is connected to a generator. READ MORE
