  1. 21. Validation of a vortex panel method for aerodynamics and aero-elasticity of Wind Turbine

    University essay from KTH/Kraft- och värmeteknologi

    Author : Antoine Thibierge; [2018]
    Keywords : ;

    Abstract : Ardema3D is a new type of vortex free model code that can simulate wind turbines. This code has been developed in order to replace the state of the art model, the blade element momentum (BEM). READ MORE

  3. 22. Some deviations from linear dynamics due to more accurate damping models

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Jakob Sjöstrand; [2017]
    Keywords : Bilinear hysteresis; Standard linear solid; SLS; Linear Dynamics; Non-linear Dynamics; Technology and Engineering;

    Abstract : Damping is present in all dynamic systems. In one way or another energy is being dissipated in the system. To capture this aspect of reality in a computational model is a difficult task. A common simplification is to assume that the damping is of a linear viscous nature. READ MORE

  4. 23. Parsing and Validation of Modelica Models Utilising Fault Diagnosis

    University essay from Linköpings universitet/Fordonssystem

    Author : Karin Lockowandt; [2017]
    Keywords : Model Validation; Modelica; Fault Diagnosis; Structural Analysis; XML; Dymola;

    Abstract : Models have become an indispensable tool within most industrial sectors and are used to reduce costs, enhance the performance of a system etc. The computer support within modelling is extensive, whereof the programming language Modelica is eminent, especially for multi-domain models.

  5. 24. Structural Diagnosis Implementation of Dymola Models using Matlab Fault Diagnosis Toolbox

    University essay from Linköpings universitet/Fordonssystem

    Author : Petter Lannerhed; [2017]
    Keywords : Diagnosis; Structural Methods; Observer Construction;

    Abstract : Models are of great interest in many fields of engineering as they enable prediction of a systems behaviour, given an initial mode of the system. However, in the field of model-based diagnosis the models are used in a reverse manner, as they are combined with the observations of the systems behaviour in order to estimate the system mode.

  6. 25. Response of Buildings Exposed to Blast Load - Method Evaluation

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Carl Löfquist; [2016]
    Keywords : Explosion; Blast Wave; Impulse; Rayleigh-Ritz metod; Ritz vectors; Computational effeciency; Modal Reduction; Eurocode; Technology and Engineering;

    Abstract : Due to accidental external explosions ,which is not handle in the Eurocodes, are structural designers looking for other ways to design loads for external loads due to explosions. This combined with lighter building structures is a reason to address the issues of analysing the dynamic behavior of buildings subjected to air blasts from these extreme situations. READ MORE
