  1. 1. 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. 2. Modeling and Simulation of Brake Squeal in Disc Brake Assembly

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Jenny Nilman; [2018]
    Keywords : Brake Squeal; Complex Eigenvalue Analysis; Model Validation; Parametric Study; High Frequency; Brake Noise;

    Abstract : Brake squeal is an old and well-known problem in the vehicle industry and is a frequent source for customer complain. Although, brake squeal is not usually affecting the performance of the brakes, it is still important to address the problem and to predict the brakes tendency to squeal on an early stage in the design process.

  4. 3. Models and algorithms for the study of traffic with delay

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Hanna Fredenklo Jansson; Ruth Aleksandrauskaite; [2016]
    Keywords : ;

    Abstract : Trac is an essential matter to examine and understand since it is a paramount aspect of modern society. The objective in this bachelor thesis is to formulate models that describe the propagation of vehicles and analyse these using the concepts of stability as well as sensitivity. READ MORE

  5. 4. Evaluation of COMSOL Multiphyscis for rotordynamical analysis

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Hessameddin Moradi Motlagh; [2012]
    Keywords : ;

    Abstract : Rotary machinery systems are widely used in different industries. As they have rotational movements, the resonances will be the function of rotational speed. READ MORE

  6. 5. Frequency Response Analysis using Component Mode Synthesis

    University essay from Institutionen för matematik och matematisk statistik

    Author : Tor Troeng; [2010]
    Keywords : Component Mode Syntesis; model reduction; frequency response analysis;

    Abstract : Solutions to physical problems described by Differential Equationson complex domains are in except for special cases almost impossibleto find. This turns our interest toward numerical approaches. Sincethe size of the numerical models tends to be very large when handlingcomplex problems, the area of model reduction is always a hot topic.
