Enhancing lateral stability of bidirectional virtual track trains through articulated rotation systems

This paper investigates the mechanism and optimization of the articulated rotation system to enhance the lateral stability of bidirectional Virtual Track Trains (VTT), an innovative rail transportation technology that utilizes virtual tracks instead of physical ones. Through a combination of theoretical analysis and multibody dynamics simulations, the study explores the effects of articulation stiffness and damping on vehicle stability and curve negotiation. Results indicate that increasing articulation stiffness reduces trajectory deviation and the rate of change in lateral deviation, while damping affects the convergence rate without altering stability. The optimized articulation system significantly improves stability and maneuverability, contributing to safer and more efficient operation of VTTs.
