Open full text 2 citations

Abstract

The authors developed a bogie which has independently rotating wheels and weighs half as much as the conventional one, with the intention of improving the stability of high speed running on tangent section and the curving performance. The performance of the bogie was tested on roller rig and in filed tests. From the measurement, it was verified that the independently rotating wheels using a newly developed wheel profile has a gravitational restoring force and performance level that was expected. From eigenvalue and results of simulation, the influence of modeling level and that of the steering mechanism, and the better running stability of the independently rotating wheels are clear.
