  1. 1. Dynamic Analysis of a Window connected via the Click-In System

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Abhikaran Bhatia; [2022]
    Keywords : Finite Element Modelling; Vibrational Analysis; MSC Nastran; MSC Apex;

    Abstract : It is often needed to predict the behavior of structures. With the helpof an FE model, it is possible to see the motion of the structure. Inthis, Master thesis work time domain analyses were carried out on afinite element model representing a window attached by click-ins. READ MORE

  3. 2. Automatic data processing of traction motor measured data and vibration analysis of test bench

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Arshey Dhangekar; [2021]
    Keywords : Electric motor; Traction motor; MATLAB; data processing; data analysis; COMSOL Multiphysics; FEM; test bench; natural frequency;

    Abstract : One of the goals of ABB AB is to develop highly efficient electric motors for traction application. The demand for traction motors is increasing due to the rise in electric vehicles sale and railway locomotive engines. READ MORE

  4. 3. IR spectroscopy for vibrational modes : A semi-classical approach based on classical electrodynamicsand modern quantum mechanics

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Ulf Oreborn; [2018]
    Keywords : ;

    Abstract : The atoms of a molecule are always restless and are constantly moving in one way or another.Apart from rotations and translations, they may vibrate in many different modes. They may moveradially toward or from each other, so called stretching. This can be done symmetrically or asymmetrically. READ MORE

  5. 4. A comparative study regarding weakly stationarity assumptions and time dependency : Signal processing of vibrational loading and its influence on fatigue life

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT); Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Rikard Dahlman; Ebba Johansson; [2018]
    Keywords : Stationarity; Test for weakly stationarity; Reverse arrangements test; Runs test; Signal processing; Fatigue life; Time dependency; Piecewise weakly stationary.;

    Abstract : Simplifications regarding calculations of fatigue life due to vibrational loading is based on weakly stationarity assumptions which is a time independent method. The hypothesis was based on the uncertainty of these assumptions. The aim of this study was to examine whether the analysed data fulfilled the assumptions of weakly stationarity. READ MORE

  6. 5. FTIR- och Ramanspektroskopi som analysmetod för den kemiska sammansättningen av granved : en jämförelse

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Edward Carlsson; Douglas Kärrholmen; [2018]
    Keywords : vibrationsspektroskopi; korsvalidering; vedkemi; absorbtion; närinfraröd;

    Abstract : Den kemiska sammansättningen har en central påverkan på egenskaper och användningsområden för trä. För att kunna uppfylla dagens krav för vedens kemiska sammansättning krävs billiga och effektiva analysmetoder. READ MORE
