Advancing Lubrication Simulations for Test Rigs
The second paper, published in "Lubricants" by Franco Concli and Marco N. Mastrone from the Faculty of Engineering, Free University of Bolzano/Bozen, presents an advanced numerical study on the optimization of the lubrication system in a test rig designed for RCF experiments. This pioneering work, within the IDERPLANE framework, introduces an entire system analysis including shafts, gears, and bearings using a Finite Volume Computational Fluid Dynamics approach. The study successfully optimized the nozzle orientation to maximize lubrication capability, thereby enhancing the reliability of the test rig for conducting RCF tests
These publications not only contribute significantly to the scientific community by filling a gap in literature regarding RCF and lubrication in aerospace gear systems but also underline the IDERPLANE project's commitment to pioneering research for safer and more reliable aerospace applications. We extend our gratitude to the European Union for funding this essential research and look forward to further advancements in this critical field.
Stay tuned for more updates on our project’s progresses.

Deliverable abstract:
This report summarizes the work done by Brescia University (Prof. A. Mazzu) and INSA Lyon (Prof. J-Y Buffiere and Dr C. Xiao) within the project IDERPLANE to characterize in 3D the formation of sub surface cracks during rolling contact fatigue tests performed using a bi-disk test configuration. To foster crack initiation, two cylindrical artificial defects with various depth and diameters were machined on the rolling track. Two materials conditions (heat treated and untreated) and various normal pressure P were investigated. The tests were stopped when a spall on the rolling track was detected or when a given number of cycles was reached (10^6 or 10^7 ). Thin slabs containing the surface of the disk close to the defects were cut from the disks and characterized using X-Ray tomography. Two types of X-ray sources were used: laboratory source, synchrotron source. The crack size was measured for each specimen at the bottom of the hole along two orthogonal directions. The 3D reconstructed images are available at https://doi.org/10.5281/zenodo.6351387
