Energy efficiency is a relevant topic in today’s industrialized society. With this in mind, the competition
Delsbo Electric has been organized in recent years, a competition aimed at designing the most energyefficient
rail vehicle. This bachelor’s thesis has investigated the possibilities of designing and constructing
an energy-efficient rail-bound vehicle that can participate in the competition. Based on mechanics and
electronics, different subsystems have been designed and implemented.
According to the competition’s participation rules, requirements for the vehicle’s respective parts have
been formulated. Using simulation models, the operation of the vehicle has been simulated along an estimated
track similar to the competition track. Results from these simulations have been used as a basis for
decision-making regarding the vehicle’s electrical components. Through a product development process,
different concepts have been developed based on the specified requirements. The various components
have been dimensioned through calculations and simulations and then manufactured or purchased. The
subsystems have been adapted to work together and be modular.
Once all the respective parts for the vehicle had been designed and delivered, they could be assembled
into a complete vehicle. However, the shell that would enclose the passengers was never completed and
therefore could not be implemented. To verify how well the vehicle met the requirements that had been
set, a bench test in a lab and a physical driving test were conducted at Jernhusen in Fj¨allbo, outside
Gothenburg. During the tests, it was observed that the powertrain was able to drive the vehicle forward
safely with six passengers at a speed of 14.4 km/h. No exact data on energy consumption could be
measured from the test drive as no complete measurement unit was available. To make this possible,
further development of the vehicle’s control system is necessary so that it can be driven with more
continuity.
