Abstract [en]

One of the ideas selected for development in the Green Train research and development programme is active secondary suspension. Bombardier Transportation, Sweden, has with support of KTH designed and tested both active lateral suspension (ALS) and active vertical suspension (AVS) that can improve the ride comfort and make higher speeds possible on existing tracks. The two active suspension systems were evaluated with passengers to allow KTH Railway Group to capture their perceived differences in ride comfort.

Our conclusion is that active secondary suspension (ALS/AVS) improves perceived comfort and makes it easier for passengers to move about the train while it is motion while an increase in speed (from category B to category C) has an opposite effect of approximately the same magnitude. This shows that active secondary suspension can contribute to permitting higher speeds on conventional lines with imperfect track geometry.

The higher uncompensated lateral force on bends resulting from higher speeds (category C), however, makes it significantly more difficult to move about the train for travellers with reduced mobility and this needs to be taken into consideration.
