Framtagning av aktiva hinder för testbanor
Skellefteå Drive Center vill ha hjälp med att ta fram ett väjningshinder till deras testbana för fordon. Hindret ska kunna användas året om, bli ett överraskningsmoment för föraren, vara anpassat för både personbilar, bussar och lastbilar samt får inte skada fordonet. I litteraturstudier undersöktes vilka hinder som finns på marknaden idag. Efter en bedömning mot kravspecifikationen fick en variant av vattenhinder högst betyg och valdes att utveckla. Resultatet blev ett hinder som under sommarförhållanden sprutar vatten och under vinterförhållanden snö.
Gabioner - Ett alternativ vid vägbanksbygge i lösa leror
The use of gabions means a reduced amount of filling material in the road section and a more narrow construction. Also the use of limestone cement columns can be reduced. All together this results in lower costs. The columns stand for about 55% of the total costs for the road. If gabions are used you can reduce the total costs with over 10%..

Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

Släpslangspridning av gödsel, kan det löna sig? :
I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has.
The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time.
I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today.
What is drag hose system?
You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.
Testbänk för motorbåtsdrev
Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.
