Abstract [en]

This paper describes the development of new running gear technology for future high-speed trains within the Swedish development programme Gröna Tåget (Green Train). Three different technologies are developed and tested: a passive radial self-steering "soft" bogie, an active lateral suspension including also a Hold-Off-Device function and a mechatronic bogie actively controlling the wheelset motions with actuators attached to the bogie frame. In contrast to other high-speed train developments, focus is here the challenge of balancing the contradictory demands of good running behaviour at high speeds on straight track on the one hand and good curving performance with low track and wheel damage and maintained good ride comfort on the other hand. Results are presented which confirm that all three technologies in almost all aspects meet the goals set up in the beginning of the project.
