Abstract: Vibration-induced noise in train cars is an area that receives a great deal of interest at the moment. Due to economical and environmental issues, manufacturers are cutting the weight-budget for future trains to achieve a lower total life-cycle cost. This has a negative impact on the interior noise and passenger comfort and to be competitive new methods to reduce the negative side effect are sought.

This paper describes an active control approach to isolating the car from bogie vibrations in such a way that the noise inside the car is reduced. An active control system with four inertial mass actuators fitted to an experimental light weight bogie were used to control bogie vibrations and noise inside the car. Several tests were performed in both a lab environment and on track at full speed.
