Active vibration reduction in a light weight high speed train bogie
Vibration-induced noise in the car of train is of great interest since low weight is important, but makes the structure more resonant. One excitation source is the sleeper frequency which gives rise to a periodic excitation. This paper describes an approach to isolate the vibrations caused by the sleepers in such a way that the noise inside the cabin is reduced. An LMS algorithm with four inertial mass actuators fitted to the bogie with control microphones placed in the cabin. The tests were performed on an experimental light weight bogie fitted to a test car, in both lab environment and in full scale tests on track at full speed (200 km/h).
