UIC comfort tests: Investigation of ride comfort and comfort disturbance on transition and circular curves
Swedish National Road and Transport Research Institute.
2003 (English)Report (Other academic)
Abstract [sv]

The work was first proposed by the high-speed division of UIC, and taken over

by the working group "Improvement of passenger train performance on

conventional lines". The idea was that it should be possible to improve the

commercial speed on a given line, without too much investigation. One

possibility was to increase the speed in curves without taking any other

action, which will increase the lateral acceleration experienced by the

passengers. Increasing the cant in circular curves was also a solution, using

tilting train bodies was a supplementary possibility. What are the

supplementary constraints on the passengers? The centrifugal forces are more

balanced during the ride on the circular curve, but in the transition, a

number of phenomena appear, and degrade comfort. On some occasions we know

that onset of nausea can occur.
