  1. 1. Anomaly Vibration Classification for Condition Monitoring in Passenger Cars

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Rui Zhou; [2023]
    Keywords : ;

    Abstract : 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.

  3. 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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

  4. 3. Condition monitoring of rotating machinery : A statistical approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fabian Hedin; Tim Gisseman; [2021]
    Keywords : Condition monitoring; Vibration analysis; Fault detection; Predictive maintenance;

    Abstract : 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. READ MORE

  5. 4. Energy-efficient Industrial processes : An investigation in the power consumption, power number, thrust force and torque requirement on a rotating bed reactor

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Kasim Ali Haji; [2021]
    Keywords : RBR Simulation; CFD models of an RBR; Energy-efficient Industrial processes; Power number; Power consumption; RBR; rotating bed reactor; Experimental and simulation of an RBR; Empirical models of an RBR; Thrust force; Torque requirement; k-epsilon model of an RBR; SST k-omega model of an RBR.;

    Abstract : 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.

  6. 5. Simulation and experimental study for vibration analysis on rotating machinery

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Mohd Shafiq Sharhan bin Zainal; [2020]
    Keywords : Multi Degree of Freedom MDOF ; Rotating machinery; Single Degree of Freedom SDOF ; Unbalance; Vibration analysis;

    Abstract : This student thesis aims to analyze the unbalance on rotating machinery by simulation and experimental. The machinery flywheel rotation is modelled as a Single Degree of Freedom (SDOF) and Multi Degree of Freedom (MDOF) system. The model rotation unbalance is simulated by MATLAB. Then the vibration measurement is taken by experimental. READ MORE
