1. 11. 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

3. 12. Development of a Beam for a Vibration Motor

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Kalle Nysell; Charlie Adam; [2021]
   Keywords : Finite element method; CAD; Inventor; mechanics; strength of materials; stress; development; design; Autodesk; Nastran; screen machine; material fatigue;

   Abstract : This project is centered around the use of finite element analysis for developing a beam for a new type of motor used in a screening machine. Essentially the main purpose of the developed beam is to transfer vibrations to the screen machine that it will be attached to. READ MORE

4. 13. A novel approach for the improvement of error traceability and data-driven quality predictions in spindle units

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

   Author : Adithya Rangaraju; [2021]
   Keywords : Machining; component degradation; condition monitoring; data-driven quality control.; metallskärning; komponentnedbrytning; data-driven kvalitetskontroll.;

   Abstract : The lack of research on the impact of component degradation on the surface quality of machine tool spindles is limited and the primary motivation for this research. It is common in the manufacturing industry to replace components even if they still have some Remaining Useful Life (RUL), resulting in an ineffective maintenance strategy. READ MORE

5. 14. Development of PMSM and drivetrain models in MATLAB/Simulink for Model Based Design

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

   Author : Gokul Sivaraman; [2021]
   Keywords : Electric Vehicles; Permanent Magnet Synchronous Machine; flux; flux linkage; Inductance; Model based design; Finite Element Analysis; Mechanical drivetrain; Magnetic saturation; Cross-coupling; Spatial harmonics; Temperature; Active oscillation damping; ABS wheel speed sensor; CAN bus.; Elektriska fordon; synkronmaskiner med magneter; magnetiskt flöde; induktans; modellbaserad design; Finite Element Analys; mekanisk drivlina; magnetisk mättnad; magnetisk tvärkoppling; MMF övervågor; temperatur; aktiv oscillationsdämpning; ABS hjulhastighetssensor; CAN buss.;

   Abstract : When developing three-phase drives for Electric Vehicles (EVs), it is essential to verify the controller design. This will help in understanding how fast and accurately the torque of the motor can be controlled. READ MORE

6. 15. Detection of Long Term Vibration Deviations in GasTurbine Monitoring Data

   University essay from Linköpings universitet/Fordonssystem

   Author : Johan Hansson; [2020]
   Keywords : Machine Learning; Vibrations;

   Abstract : Condition based monitoring is today essential for any machine manufacturer tobe able to detect and predict faults in their machine fleet. This reduces the maintenancecost and also reduces machine downtime. READ MORE
