Val av byggproduktionsmetod/ Praktikfall Klammerdamm : Golvgips eller avjämningsmassa

This report is about how to decide which method is the most suitable as floor covering at projectKlammerdamm in the centre of Halmstad. The covering has to be fire resistant and soundproof inorder to protect the wood structure and stop noise from traveling between apartments. There aretwo possibilities either traditional gypsum board or gypsum-based self leveling underlayment.The roads around the construction site are narrow. A regular twenty-five meter long Truck has nopossibility to reach the site. The construction site is small and the storage area is limited.

Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's Truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in Truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

Mean value modelling of a poppet valve EGR-system

Because of new emission and on board diagnostics legislations, heavy Truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

Masskattning av tunga fordon i realtid genom systemidentifiering

As Trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the Truck manufacturers. With the processing power for electronic control units in Trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

Datorsimulering av gruvlastare för funktionell testning

I denna rapport presenteras hur en simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..

Lagerprogram för Satellitlager

Texo Application has created robots that they call for satellites; with these you can feed in storage pallets into a satellite storage. Satellite storages consist of channels in height (e.g.3 to 8 pieces) and width (e.g.3 to 100 pieces). Channels can be different long (e.g. 5 to 200 pallets). At deposit of a storage pallet the Truck insert the satellite in a channel and then the pallet, the pallet is driven into the channel until it reaches another pallet or the other end.

Title Greenlighted employees ? The internal value of Schenker?s environmental work.Author David Fridner.Course Master thesis in Science of Media and Communication.Department of Journalism and Mass Communication, University of Gothenburg.Semester Spring semester 2009.Tutor Professor Monika Djerf-Pierre.Number of pages 55 (appendix 23).Aim The aim is to study the internal value of Schenker?s environmental work.Method Qualitative and quantitative method.Material 20 interviews from four workgroups: managers (4), sales (5), customer-services (4) and Truck drivers (7). 148 websurveys from two workgroups: sales (106) and customer-services (42).Main result Schenker is perceived as an environmentally friendly enterprise. Much due to the fact that the company?s impact on nature only has little to do with how the staff evaluate its ?greenness?.

Hållfasthetsanalys av gaffeltruckar

Det här examensarbetet har utförts inom civilingenjörsutbildningen för Maskinteknik vid Linköpings tekniska högskola i samarbete med SB Truck AB. Syftet med examensarbetet var att undersöka ett antal Truckmodeller för att bestämma infästningsbultarnas belastning samt hur spänningarna fördelas i de olika stativen. Infästningsbultarna håller ihop stativet och chassit.För att kunna genomföra beräkningarna med varierande stativlängder har ett excel-blad utformats, där det är möjligt att beräkna både krafterna på infästningarna och den totala förskjutningen.Belastningarna på modell TTFYI har beräknats både för hand och i Pro Mechanica. Resultaten för beräkningarna blev 3,9 kN respektive 3,7 kN. Resultat för övriga stativ finns tabellerade i resultatkapitlet.Spänningarna blir generellt sett låga i samtliga stativ på den analyserade modellen.

Föroreningar orsakade av stenar inblandade i barrmassaved

Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on Trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.

Dagbrottsdesign med IPCC

Mager är ett fiktivt gruvprojekt i planeringsfas och utvärderingar har gjort över projektet som visade att projektet är lönsamt. Boliden vill se om Mager kan stärkas ekonomiskt genom att tillämpa fullt mobil In-Pit Crushing and Conveying (IPCC). IPCC avser att förkorta ledtiden mellan grävare och kross genom att placera en kross innanför dagbrottets gränser och sköta materialtransporten ut ur gruvan med hjälp av ett transportband. Förkortningen sker antingen genom att förkorta körtiden för Truckarna från grävare till kross eller genom att helt eliminera Truckarna. Det finns tre stycken IPCC-system, stationär, semi-stationär samt fullt mobil IPCC.
