Overview

Tribology, lubrication, wear and contact mechanics are all significantly important angles of modern engineering. They affect system’s efficiency by affecting the frictional losses in contacts such as bearings, gears and seals. Durability, life and reliability of engineered systems are directly impacted by integrity of their contacts and wear. The system’s dynamic is also influenced by the stiffness and damping in contacts, prescribing the overall behaviour of the system. The abovementioned aspects are not only applicable to traditional mechanical components; but also to wider applications such as bio-mechanical systems including artificial joints.

The role of simulation and numerical methods in prediction of tribological behaviour has never been more crucial considering the necessity for moving towards zero-prototype approach in engineering developments. The computational methods can also greatly support development of green and sustainable products by controlling frictional losses and wear. Despite the significance of simulation in tribology, the numerical methods in this field are less commercialised in comparison with general purpose finite element or CFD tools.

In this webinar, following subjects related to simulation in tribology will the covered:

  • Some of the most common applications of tribological simulations in modern engineering will be discussed.
  • The theoretical classification of different types of contacts and lubrication regimes in the context of above applications will be outlined. This classification is important for selecting the appropriate numerical techniques.
  • Tribology requires a multi-physics and multi-scale system of methods. Different physics and scales which should be covered by any simulation platform will be discussed.
  • A case study of gear pair and roller bearing in an electric powertrain will be presented, demonstrating the logical workflow for a successful simulation.
  • Future trends in the field of computational tribology will be summarised.
