This paper investigates whether it is possible to develop a wheel profile design that will extend wheelset life compared to an existing commonly used Great Britain passenger wheel profile,...

The EPS profile is described in EN 13715 as ‘equivalent to profile P8 of the United Kingdom with a flange 30 mm thick’. The variant shown below has a 30 mm wide / 30 mm high flange.

The profiles have been created mainly for testing purposes. DSB_82 Wheel profile designed by the Danish State Railways, suitable for a rail inclination of 1/20. N33 Wheel profile designed by the Swedish State Railways, suitable for a rail inclination of 1/30. P8 Wheel profile designed by Brittish Rail, suitable for a rail inclination of 1/20 ...

Jun 1, 2022 · A ‘Reduced Flange Wear’ (RFW) wheel profile has been developed, based on the P8 profile but with a modified flange root geometry. The Wheel Profile Damage Model has been used to calculate how the proposed RFW wheel profile could reduce wear rates and therefore increase wheelset life.

It demonstrates how a Wheel Profile Damage Model (WPDM) can be used to accurately predict both the magnitude of wheel wear and the worn shape of the wheel for mileages exceeding 100,000 miles since turning. The paper presents results for …

Apr 20, 1991 · Wear of the P8 wheel profile The P8 wheel profile is a hollow profile that under some conditions retains a remarkably constant conicity as it wears. In other cases the conicity rises or falls according to the interplay between suspension stiffness and route curvature.

NR wheel profiles, such as the BR P8, are not suitable for use on SST infrastructure as the wider flange leaves insufficient flangeback clearance to the keeper rail to allow the wheelset to steer effectively in curves. Figure 2 shows an SST and a BR P8 wheel profile on a grooved rail section.

Size of Wheel Profile Rim Edge Chamfer. P5 wheel profile with thinner flange. (extension of 08/172/TNC). GMRT2466 issue 2 mandates requirements for the design, manufacture and maintenance of wheelsets and their components.

This project reviewed the recommendations from previous ARUP/Transport Technology Center Inc research regarding hollow wear limits and false flange damage on stock rails caused by P8 wheel profiles.

This investigation focuses on creating a new wheel profile for passenger vehicles, based on the P8 wheel profile, but using a different flange root shape in order to reduce flange wear rates.
