1. Utvekling av blåmärkningsverktyg för högpresterande kuggväxlar
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Detta projekt undersöker möjligheten att utveckla ett nytt verktyg för blåmärkning av kuggväxlar. Projektet görs i samarbete med Siemens Energy i Finspång som bland annt tillverkar Gasturbiner för energiförsörjning. Gasturbinerna förses med högpresterande växellådor som dimensioneras för att klara av stora belastningar. LÄS MER
2. Test rig for gear transmissions in electrical applications
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Due to the environmental problems associated with fossil fuels and a big need from the market, the majority of the automotive industry is going towards fully electric vehicles (EVs). To further reduce the environmental footprint there is ongoing research on the use of fossil-free lubricants, if they could be used to lubricate the drive train which could further reduce the use of fossil oil in the automotive industry.

3. Designing of two load bearing surfaces in a modern high-speed steam engine
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : The topic of this thesis is the designing of two load bearing surfaces in a modern high-speed steam expander. One of the surfaces is a synchronizing gear structure and the other a conical surface. The goal besides the design is to calculate the contact pressure these surfaces experience during operation.

4. NVH analysis and optimization of electric powertrain
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. LÄS MER
5. Analysis of design requirements for early failure detection in a gear test rig
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Gears are the heart of many machines, being its function transform and transmit torque. This work is a study of adequate design requirements, in particular, the best methodology to early detect gear fatigue failure using a gear test rig, an FZG test machine. LÄS MER
