SUMMARY:Centrifugal vibration absorbers and some applied mechanics history
  - Professor David Newland\, CUED (emeritus)
DTSTART:20150313T160000Z

CONTACT:Claire Whitaker
DESCRIPTION:To meet emission targets\, car engines have become smaller and
  more highly-powered than they used to be. Lighter engines are more prone 
 to vibration and that has led to the introduction of centrifugal pendulum 
 vibration absorbers to reduce noise and wear. The history and design of th
 ese curious devices will be described. Current problems with their use as 
 a component of dual-mass flywheels (a standard part of most modern cars) w
 ill be discussed and recent research results described. The talk will incl
 ude extracts from a video of the late Professor Den Hartog of MIT lecturin
 g on this subject in the 1970s.
