Sponsor Organisations:

  • Rail CRC


Objectives

The aim of the project was to improve wagon curving dynamics, reduce wheel wear and noise by improving the management of centre bowl friction . Enabling objectives include:

  1. Evaluation of the benefits from bogie rotation friction management;
    • Low friction liners
    • Wear plate liners
    • CCSB systems
  2. Identifying alternative high serviceability bogie rotation friction management products for a range of friction levels. Product types:
  3. Serviceability test procedure for center bowl liners
Bogie Rotation 2


Background

The testing of bogie rotation resistance is supported by simulation studies of bogie rotation in curving. The project is integrated with the Rail CRC - Theme #1 - Smart Train Project. It is the first known test rig to monitor three piece bogie warp (lozenge) during rotation testing as well as being capable of monitoring and applying twisting loads and motions on the wagon.


Outcomes

This project will deliver improved knowledge of the bogie rotation friction in cylindrical centre bowls and with CCSB. The testing will determine the centre bearing rotational friction variations due to tilt movements of the centre bowl. The bogie warp stiffness and damping characteristics associated with bogie rotation friction is expected. Also performance parameters on CCSB performance will also be determined. Alternative centre bearing liner materials will also be tested and evaluated. The results will be used to improve centre bearing models used in vehicle dynamics modeling.
