Free Valve Technology : ? Utveckling av ett styrsystem för ett elektronisk styrt pneumatisk-hydraulisk ventilsystem på en förbränningsmotor

Detta examensarbete är utfört på uppdrag från AVL Södertälje Powertrain Engineering AB.Målet med arbetet har varit att utveckla ett styrsystem för ett elektroniskt styrt pneumatiskhydraulisktventilsystem på en encylindrig förbränningsmotor i en testcell. AVL är enoberoende firma som utvecklar drivlinor med förbränningsmotorer samt instrumenterings- ochtestsystem. Ventilsystemet, med ett fungerande styrsystem, ska användas i AVLs utvecklingsochforskningsarbete på förbränningsmotorer.Ventilsystemet,Free Valve Technology, är utvecklat av Cargine Engineering AB och består avelektroniskt styrda pneumatisk-hydrauliska aktivatorer som opererar en motorventil individuellt.Aktivatorernas styrsystem har utvecklats helt iSimulink och implementerats som en integreraddel i det av AVL utvecklade motorstyrsystemet Raptor. Hårdvaran och plattformen är ett rapidprototyping system från dSPACE GmbH. Systemet har visat sig fungera tillfredsställande i entestcellmiljö vid lyfthöjder större än 3 mm och varvtal lägre än 2500 rpm, även underförbränning.

Ensamkommande flyktingbarn i media : - en diskursanalys

This research intends to study the media's representation of unaccompanied refugee children on the basis that the media has a power in the construction of society.

Vätgas och bränsleceller : Ny energi för Försvarsmakten?

The purpose of this paper is to identify the current status of fuel cell technology and to establish whether said technology is mature enough to be implemented into the Swedish Armed Forces. The question to be answered in this paper is as follows: Can hydrogen gas and fuel cells be used as an alternative source of energy within the Swedish Armed Forces?This paper is based on theoretical studies and reports from prior research done on fuel cells. By studying these facts a predictive answer has been obtained. The answer I have come to, is that the maturity of fuel cell technology is currently inadequate for the Swedish Armed Forces to implement, especially considering its harsh working conditions..

Jag är teknisk : Ett stöd i teknikundervisningen

Teknikämnet har, sedan det fick en egen kursplan, åsidosatts i skolorna. Deltagande observationer och intervjuer med lärare verksamma i varierade åldersgrupper, visade samma resultat gällande tankar kring teknikundervisningen som de uppfattningar som litteraturstudien visat. Det framgår att många lärare inte uppfattar sin ämneskompetens som tillräcklig och att de inte vet hur de ska förhålla sig till ämnet i undervisningen. Resultaten av dessa studier ligger till grund för ett läromedel, bestående av en elevbok och en lärarhandledning, som utgår både från Lpfö 98 och centrala innehållet för år 1-3 och 4-6 ur kursplanen i teknik i Lgr 11..

Bjälklag i FRP-material

Syftet med detta examensarbete är att vidareutveckla glasfiberbalkar så de kan användas som mellanbjälklag i småhus. Förebilden var ett ?Delta Deck? som utvecklats av Altakor Group och används i brokonstruktioner. Denna profil har vi sedan modifierat och optimerat för bruk i småhus. Den största skillnaden är att vi valt att inte använda den så kallade ?snap-fit?-tekniken.

Effektivisering av byggproduktion med VDC och förstärkt verklighet : Streamlining construction work with VDC and augmented reality

Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase.
