STUDY ON DYNAMIC CURVING BEHAVIOR OF TILTING PASSENGER CARS

摘要

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.
