Magnetics and Experimental Results of Maglev-Vehicles

The beginning of the attractive magnetic levitation technic was in the year 1935 when H. Kemper [1] succeeded in his first private experiment on electromagnetic levitation. Further systematic research and development work he did at the “Areodynamische Ver

PREFACE

High-speed ground transportation requires the development of vehicle systems with better and better dynamical behaviour. Such vehicle systems include the guideway, the vehicle itself and the passenger or freight, respectively. The present volume contains the courses and lectures presented at the International Centre for Mechanical Sciences at Udine, in fall, 1981. All the main aspects of high-speed vehicle engineering are summarized with respect to the dynamics of automobiles, railways and magnetic levitated vehicles. Analytical, experimental and numerical methods are applied using the deterministic and stochastic approach of dynamics. The contributions to the vertical motion of vehicles (K. Popp, W.O. Scbieblen and P.C. Muller) are followed by more specific papers on the horizontal motion. Automobiles (P. Lugner, A. Zomotorand W.O. Scbieblen), railways (P. Meinke, A.D. de Pater and P. Meinke) and maglev vehicles (G. Bobn, W. Cramer and K. Popp) are treated in detail. I hope the contributions presented will be of interest to engineers and research workers in companies and univerties who want first-band information on the present trends and problems in this important field of technology. Finally, I would like to thank the authors for their efforts in presenting the lectures and preparing the manuscripts for publication. My thanks are also due to Professor G. Bianchi, Secretary General of CISM and to Professor H.B. Pacejka, Secretary General of lA VSD, for advice and help during the preparation of the course. I am also grateful to my secretar_y, U. Wachendorff, for her engaged service with respect to the editorial work.
