On synchrophasing control of vibration for a floating raft vibration isolation system
(2014-01-01)
A large-scale floating raft vibration isolation system installed on a flexible hull-like structure is described in this paper. Four vibration exciters, in which two counter rotating shafts with the same balanced masses are ...
On the spectrum of rail vibration generated by a passing train
(2017-01-01)
Recent work in rail vibration has investigated methods for estimating track support stiffness from trackside vibration. This vibration, induced by the passage of a train, is mainly due to the load applied by the wheels, ...
