  1. 1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Joel Fransson Forsberg; [2023]
    Keywords : Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Abstract : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. READ MORE

  3. 2. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

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

    Author : Muhammad Hashir Zaheer; [2023]
    Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

  4. 3. Condition monitoring of a linear rail and carriage system through vibration analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Johan Hultenheim; [2023]
    Keywords : ;

    Abstract : Condition-based maintenance is a highly relevant topic as its implementation can save both components and man-hours. Downtime is often expensive in industrial environments because machines are expensive investments; often, the machines are also part of a larger production line where it is of great importance that no bottlenecks occur.

  5. 4. 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

  6. 5. 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
