PhD topic – Axle-bearing maintenance optimisation

Matthew Pozzebon

Research summary

As part of the Qtectic consortium, Bombardier Transportation has a 30-year contract with the Queensland Government to build and maintain their New Generation Rollingstock, where the axle bearings and bogies on which the axles are located are maintained every eight years. In response, this project examined methods to model and predict lubrication needs for axle bearings to determine an ideal maintenance timeframe.

Expected completion date

October 2020

Key achievements

  • Development of a model to predict lubricated wear in bearings.
  • Application of that model to assist in predicting the impact of maintenance activities on bearing health.
