dc.description.abstractThe student race Delsbo Electric 2016 is held 28th of May. The race consists of a course of 3.36 km which is a part of Dellenebanan. The aim of this race is to travel this course and consume the least possible amount of energy per person and kilometre. In 2015 the energy consumption was measured to 1.26 watt hours per person and kilometre [Wh/pkm] for the winning team. This project is a bachelor thesis at the department of Energy and Environment at Chalmers University of Technology and aims to design an energy efficient rail bound vehicle to participate in the race. This project is supposed to be repeated yearly, and the following students should be able to improve from this project. To be able to create an energy efficient vehicle, a specification was made which consisted of requirements that the vehicle had to fulfil. The foundation to the design and different components of the vehicle consisted of simulations and theoretical models. The simulations were also used to estimate the vehicles energy consumption. The function of the finished vehicle was tested and the real energy consumption was measured during a test run. The energy consumption was later compared to the simulated values to evaluate if the simulations were made correctly. The vehicle moved steadily on the rails during the test run, and was able to get through the rail switch which was a demand since a switch appears on the race course. The energy consumption at the test run was measured to 1.76 Wh/pkm. The simulation of the test run resulted in 1.82 Wh/pkm when assumptions of completely flat ground was made. However, small variations in the inclination did effect the energy consumption in the simulations distinctly. This project resulted with a vehicle that fulfils the specifications which enables the project group to participate in the race. The energy consumption was, using the simulations tools, estimated to 3.4% deviation from the test run. This estimate is though unsure due to unknown parameters during the test. For the students that will further develop the vehicle the following years, there are many ways to improve the energy efficiency of the vehicle. It is first and foremost the weight of the vehicle that can be cut, but one could also increase the number of passengers on the vehicle to improve the energy efficiency. Constrains that were of significant value to this project were that the energy efficiency did not have any demands to result in a first place in the race. This constraint is set because the experience within the project group is far less then compared to schools that have been participating earlier years. No results from the race will be presented, due to the fact that the date of the race takes place after the report’s completion.
