Dynamic model of freight wagon
The Swedish iron ore company LKAB uses freight wagon to transport iron ore from the mines in Kiruna and Malmberget to Luleå and Narvik. Within a research project at KTH Rail Vehicles a simulation model of the freight vehicle has been built up within the Multibody simulation code GENSYS. This work is...
