Abstract
In the design of railway bogies, the compatibility between curving performance and running stability is important. Especially, there are a lot of tight curved sections in LRTs. Bogie with independently rotating wheels (IRW) could be useful to realize both curving performance and running stability. For example, EEF bogie and IRW with inverse tread conicity have been proposed. In this paper, a new-type IRW with oblique axle is proposed and the equation of motion is derived. Characteristics of hunting motion for the new-type IRW are investigated with the eigenvalue analysis. Furthermore, full vehicle model simulation with the new-type IRWs is conducted to evaluate curving performance of the proposed IRW.
