Research on the Dynamics Performance of the Radial Bogie of 200 km/h Speed raised Passenger Cars

Adopting the radial bogies is an effective way to improve the curving performance of railway vehicles. In this paper, the application and development of the radial bogie are briefly introduced, and the guiding mechanism and the structure modes of the radial bogie are expounded. According to the fundamental principle of self-steering bogies, the basic scheme for the radial bogie of speed-raised passenger cars is put forward on the basis of the several existing self-steering bogies, and the dynamics model is established. The dynamics performance is analyzed and calculated by using SIMPACK simulation program and is compared to that of ordinary bogies. The theoretic analysis and calculation results show that self-steering bogies may effectively improve negotiation performances and wheel-rail wear of speed-raised passenger cars.
