| Summary: | Aiming at the security of the certain 200 km/h speed level B0-B0 passenger locomotive transport across the line, dynamic model of the locomotive was established with multi-rigid-body dynamics software SIMPACK. Under the conditions of using different thicknesses rim standard tread, and the tolerance limit of dedicated passenger railway track and back-to-back distance of the wheelset, four working conditions of the wheel/rail limit gap were completed dynamics analyses. The results showed that the horizontal stability, straight and curve negotiation of the locomotive could meet the requirements of safe operation under the working conditions of the wheel/ rail limit gap; with the increase of wheel/rail clearance, the locomotive dynamics performance became worse, especially for horizontal performance. |
