eng	Semi-active damping system for secondary suspension of electric multiple unit	In this paper, a project of research and development of a semi-actively controlled damping system for an electric multiple unit and its current results are presented. The aim of the project is to develop and manufacture a set of fast magnetorheological dampers including its control, which can be applied in secondary suspension of an (inter)regional electric multiple unit as vertical and lateral dampers, and validate the expected contribution of this system for improvement of vehicle running comfort by operational tests. For purposes of assessment of efficiency of the considered control algorithms and tuning of their parameters, multi-body simulations were used. Besides to that, full scale laboratory tests of secondary suspension system in vertical direction on a dynamic test stand were used to verify the expected effects of the semi-actively controlled dampers.	electric multiple unit; secondary suspension; magnetorheological damper; semi-active control; multi-body simulation; full scale test; running comfort
