  1. 11. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

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

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

  3. 12. Wood and moisture-induced strains in a large deformation setting in 3D

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Fredrik Ström; Anwar Obeido; [2022]
    Keywords : Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

  4. 13. Concept Design Improvement of Shift Fork for New Dog Clutch Actuator : Simulation driven product development approach

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Nirmal Srinivasan; [2021]
    Keywords : Product development; Dynamic analysis; Equivalent-static load; Finite Element Method; Fatigue analysis; High-Pressure Die Casting; Computer-Aided Engineering; Computer-Aided Design; Topology optimization.;

    Abstract : Kongsberg Automotive is developing a brand-new actuator for engaging and disengaging a clutch for different driveline applications. This master thesis research improves the concept design of the shift fork for the new Dog-Clutch Actuator using Design for Manufacturability (DFM). READ MORE

  5. 14. Door closing sound quality related to door sealing stiffness

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Riccardo Derton; [2021]
    Keywords : Door Closing Sound Quality; Customer’s Perspective; Psychoacoustics; Acoustic Analysis; Wavelet Analysis; Artificial Head; Door Closing Motion; Door Seals; Door Sealing Stiffness; Stiffness Analysis; Ljudkvalitet vid dörrstängning; Kundperspektiv; Psykoakustik; Akustisk analys; Wavelet analys; Konstgjort huvud; Dörrstängningsrörelse; Dörrtätningar; Styvhet i dörrtätningar; Styvhetsanalys;

    Abstract : The door closing action is a recurrent situation when using a vehicle, and its sound is therefore a common sensation, which would elicit pleasant feelings. Sensory pleasantness is an important aspect in terms of customer’s perspective, and it can be a contributing factor when deciding to buy or not a specific vehicle. READ MORE

  6. 15. Validating Discrete Event Simulation as a tool for short-term scheduling in dynamic environment

    University essay from KTH/Hållbar produktionsutveckling (ML)

    Author : Naga Venkata Someswara Chandra Peri; Lena Skog; [2021]
