1. Parameter study for an energy efficient suspension for a rail vehicle prototype
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : The push for sustainability in all parts of our society has never been as big as it is currently. One project that aims to produce sustainable innovation in the railway industry is the Delsbo Electric competition where some of the world’s most energy efficient vehicles compete. READ MORE

2. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport
University essay from KTH/Bro- och stålbyggnadAbstract : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. READ MORE

3. Dynamic Simulation and Suspension Optimization for a Heavy Duty Railway Bogie
University essay from KTH/SpårfordonAbstract : A multi-body simulation study was undertaken to investigate the running behavior of a rail grinder vehicle with newly developed Ganz bogies. The main purpose of the simulations was to forecast and support the vehicle acceptance tests and support the ongoing development. READ MORE

4. Improving the validation of a railway vehicle model in the virtual certification process
University essay from KTH/SpårfordonAbstract : Before vehicles can be placed in service it has to complete an authorisation process. At the moment,this process is largely depended on tests. This is, however, an expensive and long process. With new technologies and improved simulations this process can be shortened and the costs can be lowered. READ MORE

5. Dynamic Modelling of the KTH Roller Rig
University essay from KTH/SpårfordonAbstract : The Rail Vehicle Research group at Kungliga Tekniska Högskolan (KTH) is on the path to design and build a scaled test rig called roller rig for research and educational purposes. A roller rig is a device simulating the track with rollers on which the test subject (a wheelset, bogie or even a full vehicle) canbe placed. READ MORE
