Dynamic Simulation of the Train Concept Nowait Transit

Sammanfattning: This thesis deals with some aspects of the Nowait Transit train concept in order to provide insight and guidelines for further development. The train constitutes an interconnected closed string of cars and requires track areas with complex rail geometry. The thesis is divided into two parts where the first part provides a strategy in order to ensure smooth passing through these zones. The main part is dedicated to simplifying the stability analysis of the interconnected system. This is done by defining a stability criteria that can easily be applied to the subsystems and that guarantees the stability of the string. Simulation models are developed continuously throughout the thesis and are used to verify theoretical results and hypothesis.
