Title of thesis: Tribo-Dynamics of Bearings for Electric and Hybrid Electric Vehicles’ Powertrains
As the automotive sector transitions towards Hybrid and Electric vehicles to meet present and future emissions demands, powertrain complexity is increasing. Coupled with the aim to achieve zero-prototype development, the use of simulation tools to accurately predict their behaviour at both component and system level is becoming more prevalent. The use of ultra-high speed and low load motors introduces new challenges regarding NVH (Noise, Vibration and Harshness) and the tribology of interacting conjunctions, especially within the rolling element bearings. The compact, light-weight and efficient motors operate under significantly different working conditions and are subject to different underlying physics; such as regime of lubrication, dynamic response and magneto-mechanical interactions. This work aims to improve the accuracy of modelling these components to contribute towards the success of simulation tools.
