PhD topic – Monitoring and control of false brinelling

Research summary

As the rail industry becomes increasingly global, the requirement to understand the effects of transport-related movement and forces on rail components is critical. Currently when bearings are being transported, a form of wear called false brinelling can occur. This project involved developing wear models and assessing bearings during transportation to understand the cause of false brinelling, so that future transportation conditions can be adjusted to ensure the bearings arrive in prime condition.

Expected completion date

December 2020

Key achievements

• Development of a Predictive Model of False Brinelling.
• Validating and Tuning of the Model against Field Measurement and Laboratory Data.
• Optimisation for Mitigation of False Brinelling.
