Requirements on high efficiency of rotating machinery forces engineers
to deal with problems of self-induced vi- brations and balancing of
rotors in a serious and scientific manner. The last decade has shown a
leap towards the solution of advanced problems of this kind as indicated
by the large amount of scientific and engineering papers on rotor
dynamics published in international journals. In appreciation of this
situation the General Assembly of the International Union of Theoretical
and Applied Mecha- nics (IUTAM) at its meeting in Moscow in 1972, acting
on a proposal by the Danish Adhering Organization, decided to sponsor an
international symposium on the "Dynamics of Rotors" . The scientific
planning of the symposium was handed by a scientific committee,
consisting of Prof. R.E.D. BISHOP, UK, Prof. S.H. CRANDALL, USA, Prof.
F.M. DIMENTBERG, USSR, Dr. A. TONDL, CSSR, Prof. H. ZIEGLER, Switzerland
and Prof. F.I. NIORDSON, Denmark, (Chairman). This committee was charged
with the selection and invitation of a small number of outstanding
scientists in the field, whose contributions to the symposium are
presented in this volume. Participation was restricted to invited
scientists and there were 87 active participants from 18 countries.
Apart from a financial contribution from IUTAM to sup- port travel and
subsistence of invited participants, generous contributions were
received from the following Danish Companies: Burmeister & Wain,
Danfoss, The Danish Sugar- corporation, DISA, Elsinore Shipbuilding
Engineer, Kyndby- v rket, Niro Atomizer, and the Swedish Company
STAL-LAVAL. The contributions are gratefully acknowledged.
