Pioneering Tool for Journal Bearing Simulations Released

In December 2024, a new Journal Bearing web application was launched on the Tribology Universe platform, presenting a practical tool for conducting mixed and elastohydrodynamic lubrication (EHL) simulations of journal bearings. 

This state-of-the-art application is tailored for engineers, researchers, and students who work in the fields of tribology and mechanical design.

The app provides an open-access gateway to powerful simulation capabilities, effortlessly accommodating both plain journal bearings and those with spiral grooves to offer the flexibility necessary for various design and analysis requirements. 

One of the app's standout features is the unprecedented level of customisation it affords users with regard to surface microstructures. Users can either choose from an expansive library of production-specific types or upload their own designs through provided sample templates, to get the simulation environment to closely mirror real-world conditions.

The customisation options extend beyond surface microstructures to the very materials used in the simulations. Users can select materials for the shaft, bushing, and lubricants from a library or to define bespoke materials, allowing for highly accurate and project-specific simulations.

This Finite Element Analysis (FEA) app goes beyond standard simulations, capturing the deformation of bearings under operational loads with remarkable accuracy. Hosted on a cloud-based server, the app efficiently delivers simulation results to users in a mere 15 minutes.

This process takes away the need for software licences, installations, or high-performance computing hardware. Users need only a standard web browser and an internet connection to access the app's full capabilities.

The app's model reproduces the mixed lubrication regime, resolving the load balance between asperity contact and hydrodynamic pressure build-up. The simulation results are thorough, providing detailed visualisations of critical parameters such as von Mises stresses, gap heights, surface contact pressures, and oil hydrodynamic pressure build-up.

The app also generates key performance indicators, including the coefficient of friction and power loss, which are invaluable for users optimising bearing performance. 

With these features, the Journal Bearing web application has become an indispensable tool for those involved in the intricate field of bearing simulations.
