The principle and characteristics of locomotive radial bogie are analyzed. The steering mechanism and structure of the locomotive radial bogie are rather complicated and have high theoretical and technical difficulty. The prospect of locomotive radial bogie development is very broad, its dynamic performance is good, the applicable scope is very wide. The steady-state and dynamic curves of locomotive radial bogie are established by calculating the model. The calculation shows that the locomotive radial bogie has good curve passing performance and adhesion performance.
