ABSTRACT
It is now well accepted that active steering can offer better trade-offs between running stability and curving performance. Different active steering mechanisms and control strategies have been proposed, and one of them is to replace the conventional solid-axle wheelsets with independently-rotating wheels. This paper presents a co-simulation method to study the benefits of using independently-rotating wheels to improve the curving performance of railway vehicles. The simulation results show that the independent-rotating wheels can provide near radial curving in curves as sharp as 12 m radius.
