Editorial Reviews

Edited versions of lectures and research contributions from the ASI in the areas of tribology and dynamics. The topics covered include physical and mathematical modeling, modal analysis and system identification, balancing, influence of bearing behavior in the dynamics of rotors, interaction with foundations, instability threshold, non-linear aspects, vibration measuring and monitoring, and specific lubrication analysis (filtration, particle monitoring, etc.). Two of the papers are in French, the remainder in English. Annotation c. Book News, Inc., Portland, OR (booknews.com)
