1. Anomaly Vibration Classification for Condition Monitoring in Passenger Cars
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : This research aims to investigate accurate classification of anomalous vibrations produced during vehicle operation. The main research questions are which data can be used as classification criteria, which models can better achieve classification effects, and how to address classification issues under different variables in a car.

2. 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)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
3. Condition monitoring of rotating machinery : A statistical approach
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Identifying faults in machinery before they cause critical failure is the core purpose of condition monitoring. This report gives a background to condition monitoring and outlines the current state of research in the field, and its most important theoretical components. LÄS MER
4. Energy-efficient Industrial processes : An investigation in the power consumption, power number, thrust force and torque requirement on a rotating bed reactor
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : Rotating bed reactors are used throughout the process industry. They are usedboth in the chemical industry and other industrial sectors, such as pharmaceuticals and the textile industry in decolorization due to by-products or contaminants.SpinChem AB manufactures rotary bed reactors (RBRs) to perform chemical reactions between liquids and solids.
