1. 16. How Does Skid Design Affect Transportability and Handling of Heavy Machinery?

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Eric Eldensjö; Isidor Söderman-Lundqvist; [2022]
   Keywords : skid mounted machinery; transportability; FEA; lashing and securing; load carrier.; rammonterad maskin; transporterbarhet; FEM-analys; surrning och säkring; lastbärare;

   Abstract : At request of the company Climeon, this study was made regarding transportability of skid mounted heavy machinery. The study aimed to investigate what constraining dimensions there might be when transporting by road and sea as well as necessary features that would accommo date lifting, handling, lashing and securing.

3. 17. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Johan Samuelsson; [2022]
   Keywords : Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

   Abstract : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. READ MORE

4. 18. Effect of the Textured Surface on Friction Coefficient

   University essay from KTH/Industriell produktion

   Author : Miguel Angel Valdivieso Muñoz; [2022]
   Keywords : Surface texture; friction coefficient; pin-on-disk; crosspatched; circumferential; Yttextur; friktionskoefficient; pin-on-disk; korspatchad; periferiell;

   Abstract : Friction continues to be one of the main causes of energy loss in mechanical systems despite the advances in technology. As a result, this not only involves energy overuse but also maintains high levels of CO2 emissions that cannot be assumed if society wishes to shift towards a more sustainable industry. READ MORE

5. 19. Evaluation of Refined Tribological Properties of Diamond Coated Cutting Tools Used in Machining of High-Strength Aluminum Alloys : Master thesis report regarding refined frictional & wear behavior of uncoated & CVD diamond coated WC-Co cemented carbide cutting tools used for machining of Al 7xxx alloys.

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

   Author : Christian Hultman; [2022]
   Keywords : tribology; machining; metal cutting; turning; milling; friction; wear; material transfer; surface technology; tribologi; skärande bearbetning; svarvning; fräsning; friktion; förslitning; nötning; materialöverföring; ytteknologi;

   Abstract : High strength aluminum alloys have for a long time been a popular material utilized in the automotive and aerospace sector due to coveted mechanical properties in terms of weight, strength, fatigue, and corrosion. However, tribological mechanisms such as tribo-film formation and material transfer during the metal cutting manufacturing process of aluminum impose significant reduction of machining and tool-life performance.

6. 20. Simulating Effects of Agent Velocity Changes on Crowd Behavior During Fire Emergency Evacuations

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Charlie Mårtensson; Jacob Brännström; [2021]
   Keywords : ;

   Abstract : Fire emergencies are both deadly and difficult to accurately model in real life. Computer-simulated crowds provide a way to observe the possible outcome of a fire emergency evacuation without endangering real human subjects. READ MORE
