POSSIBILITIES OF IMPROVING A RAIL VEHICLE RUNNING SAFETY WITH INDEPENDENTLY ROTATING WHEELS

Blog Article

This work is focused on the possible ways of improving the running safety of a railway vehicle, which uses IRWs (independently rotating wheels) in a bogie.It discusses the main positive and negative properties of an application of IRWs for a railway vehicle while it is running in a curve.There are evaluated running properties of a railway vehicle in terms of safety for 75 corvette door panels IRWs and a standard wheelset (SW).It is assumed that a wheelset design with IRWs will reduce the risk of derailment of a railway vehicle in a curve with a smaller radius because it will be reached a more favourable distribution of decisive forces in the wheel/rail contact.

A designed wheelset with IRWs differs from other IRWs designs; in this case, only a flange can rotate independently from a wheel treat surface about the axis of rotation.Further, this research presents an analysis of a friction forces distribution of the friction forces in a contact of a flange and a rail head and a comparison with an SW.The obtained results allow concluding that it is advisable to use canine spectra kc 3 intranasal single dose the wheels with the perspective wheel design (including independently rotating) to reduce the resistance to movement and improve the running properties of a railway vehicle for safety.
