1. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : 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. LÄS MER
2. Modeling and Simulation of Brake Squeal in Disc Brake Assembly
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : 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.

3. Soil-Structure Interaction of Pile Groups for High-Speed Railway Bridges
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : .... LÄS MER
4. Models and algorithms for the study of traffic with delay
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
5. Evaluation of COMSOL Multiphyscis for rotordynamical analysis
Master-uppsats, KTH/MWL Marcus Wallenberg LaboratorietSammanfattning : Rotary machinery systems are widely used in different industries. As they have rotational movements, the resonances will be the function of rotational speed. LÄS MER
