1. 1. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Författare :William Tönnberg; [2022]
   Nyckelord :Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

   Sammanfattning : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. LÄS MER

3. 2. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

   Författare :Kent Nystedt; [2022]
   Nyckelord :Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

   Sammanfattning : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. LÄS MER

4. 3. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes

   Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Musole Kambita; [2022]
   Nyckelord :Cylindrical steel tanks; yield strength; carbon steel; high strength steel; design load; buckling; stiffening rings; Finite Element Method FEM ; Linear Elastic Bifurcation LBA ; and Geometrically and Materially Nonlinear Analysis with Imperfections GMNIA .;

   Sammanfattning : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. LÄS MER

5. 4. : Inverkan av släntnära portryck på släntstabilitet : En känslighetsanalys av siltslänter längs Ångermanälven

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Katia Calming; Myrna Öttenius; [2022]
   Nyckelord :Silt; slope stability; pore water pressure; SLOPE W; Ångermanälven; sensitivity analysis;

   Sammanfattning : The stability of natural slopes is goverened by many factors, one of which is the porewater pressure. In this study, a sensitivity analysis has been conducted in GeostudioSLOPE/W to investigate the impact of near-surface pore water pressure on thefactor of safety i silt slopes. LÄS MER

7. 5. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Amir Avdic; Kishore-Babu Vejendla; [2022]
   Nyckelord :viscous losses; hydrostatic bearing; hydrodynamics; thin oil film.; Viskösa förluster; generator; hydrostatiska lager; hydrodynamik; tunn oljefilm.;

   Sammanfattning : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it. LÄS MER
