Abstract:
By using tilting carbodies, train can negotiate at a higher
speed without reducing the passenger’s ride quality. This is a
good method to allow a significant increase in speed at existing
track to improve the railway transportation capability, and to
enhance the competition ability of railways with other
transportation systems. With the increase of the curve
negotiation speed, the wheel-rail lateral forces and wheel-rail
wear of the tilting train will increase. The self-steering
radial bogie is an effective way to solve the problem. The
dynamic model of the tilting passenger car with self-steering
bogies is established in detail, and the curving performance of
the car is investigated.
Key words:
Tilting passenger car Self-steering bogie Dynamic curving
behavior Wheel-rail interaction
