Active control of high-speed railway vehicles

Abstract

This paper presents the active suspension control for bogie-based and two-axle railway vehicles. A bogie-based and a two-axle railway vehicle with solid-axle wheelsets, and a two-axle vehicle with independently rotating wheelsets (IRWs) are considered. The curving performance of each vehicle is presented and compared. The findings in this work show that the two-axle vehicle performs better during curving than the bogie-based vehicle especially when minimum wheelset lateral displacement (for reduced wear and tear of the wheelset) and control effort are of the main concern. It also has the advantage of lighter and simpler configuration. The simulation results also show that the IRW provide better curving performance than the solid-axle wheelset
