  5. 4. Modelling of air-gap harmonic torques and its impact on vibrations in electric drivetrains : Modelling interaction between electromagnetics and vibration of an electrical machine

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

    Författare :Dhiyanesh Radhakrishnan; [2021]
    Nyckelord :Electro-Magnetics; Eigenfrequency; Electrical Machine; Multi-Body Dynamics; Displacement; machine vibrations; Elektromagnetik; Eigen frekvens; Elektrisk maskin; Flerkropps dynamik; Förskjutning; maskin vibrationer;

    Sammanfattning : In this report, the effect of external torque injection of a particular phase and frequency was analyzed using an induction motor assembly consisting of a prototype of an induction motor and a flexible mounting arrangement. The eigenfrequencies of the several components that make up the construction of the induction machine assembly are found out both by analytical and FEM methods. LÄS MER

  7. 5. Simplification of CAD Geometries to perform CEM Simulations

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Farrukh Bashir; [2021]
    Nyckelord :Defeaturing; Modification; Blending Features; FEA; CEM; CAD; CAE.;

    Sammanfattning : The purpose of this study is to investigate small features in CAD geometries which have high influence on computational time and memory consumption during electromagnetic simulations using CAE software. Computational Electromagnetics (CEM) simulations of complex CAD geometries like passenger cars crash often simulations remain incomplete due to a lot of irrelevant details. LÄS MER
