Illustrated with over 150 figures, this text for researchers and development engineers (and interested graduate students) describes various practical and economical approaches to dealing with gear noise and vibration. The focus is on basic non-mathematical ideas of how vibration is generated by the transmission error and how it progresses through the system. The second edition offers new coverage of high- and low- contact ratio gears. Smith teaches engineering at Cambridge University. Annotation (c) Book News, Inc., Portland, OR (booknews.com)
