1. Simulation of Mechanical Shock with Finite Element Analysis and Estimation of Shock Attenuation
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Space equipment is often subjected to mechanical shocks. Some devices like electronics are sensitive to shocks, and they can easily be damaged. To protect these devices, it is important to study shock penetrations in space structures. The Finite Element Method is an effective tool to simulate response to transient excitations. LÄS MER
2. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure
Master-uppsats, KTH/LättkonstruktionerSammanfattning : This volume covers the phases from design to manufacturing of a wind tunnel test support structure for a conceptual blended wing-body UAV designed by KTH Green Raven Project students. The innovative aircraft design demonstrates sustainability within aviation by utilizing a hybrid electric-fuel cell propulsion system. LÄS MER
3. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och -produktionSammanfattning : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. LÄS MER
4. Design and comparison of PMaSynRM versus PMSM for pumping applications
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This master thesis aimed to design a permanent magnet assisted synchronous reluctancemachine (PMaSynRM) rotor for pump applications which were to be implemented inan existing Induction Machine stator. The machine were to be compared with a similarpermanent magnet synchronous machine (PMSM) with similar torque production in termsof cost and performance. LÄS MER
5. Thermal cracking of a concrete arch dam due to seasonal temperature variations
Master-uppsats, KTH/BetongbyggnadSammanfattning : Concrete dams located in northern regions are exposed to large seasonal temperature variations. These seasonal temperature variations have resulted in cracking in thin concrete dams. Continuous monitoring and evaluation of existing dams are important to increase the knowledge about massive concrete structures and to ensure dam safety. LÄS MER
