Carbody and Passengers in Rail Vehicle Dynamics

Abstract

Rail vehicle dynamics is a subject that is necessary to master for many rail vehicle engineers, with many practical problems to overcome. It is also a source of interesting problems for the theoretically interested. Working on this thesis I have made an effort to understand both the engineer’s and the theorist’s points of view, and I hope that both find something interesting to read here. The work is a part of the project SAMBA, an abbreviation for “SAMverkan fordon-BAna ” (Vehicle-track interaction) which was initiated jointly by the Swedish railway industry (Adtranz, SJ and Banverket) and KTH. The overall aim of the project is to deepen the knowledge of rail-vehicle dynamics to the benefit of railway industry. The present work addresses the issue of development of modelling and simulation techniques for the prediction of carbody vibrations and ride comfort. The financial support from Adtranz Sweden, SJ, Banverket and NUTEK (The Swedish National Board for Industrial and Technical Development) is gratefully acknowledged. I owe a great Thank You to my supervisor Dr. Mats Berg for his continuous and reliable support. I thank Professor Evert Andersson for his enthusiastic and efficient advice. The
