Research Area: Railway vehicle dynamics, route design, alignments design
On the basis of extensive research on the theory of orbital curves at home and abroad, the curve design principles of high-speed railways are proposed. The research obtained a complete set of new methods for the design of the orbital curve, which theoretically solves the global problems of the orbital curve design. In the form of a single curve expression, a no-round curve, a reverse curve, and a U-shaped curve whose planes reach G4 continuity and elevation reaches G2 are designed. The dynamic theory analysis under vehicle-track rigid body model shows that under 350km/h driving conditions, the derailment coefficient is less than 0.05 and the load shedding rate is less than 7%, which is far better than the current safety limit.
