Periodic Reporting for period 1 - PATRON (The Doctoral Network on Prognostics and heAlth management of nexT GeneRatiOn drivetraiNs)
Periodo di rendicontazione: 2024-02-01 al 2026-01-31
Europe’s industrial sector creates fantastically complex machines that rely on the synergy of multiple disciplines, such as mechanics, materials science, electronics, mathematics, and computer science. Moreover, the arrival of new technologies as part of Industry 4.0/5.0 Aviation 4.0/5.0 and Agriculture 4.0/5.0 lead to the new generation of drivetrains. PATRON will promote cooperation between top European universities, research institutes, OEMs and industrial stakeholders with an expertise in mechanical engineering, tribology, signal processing, computer science, vibrations, operations & maintenance and data analytics. PATRON will train the new generation of European expert engineers and scientists in the field of Prognostics and Health Management (PHM) for online, on-time, accurate monitoring/fault detection/diagnosis/prognosis for next generation drivetrains for better safety, minimal environmental impact, as well as production and energy efficiency.
PATRON will pave the way for Prognostics and Health Management of the new generation of drivetrains, answering to the hot European industrial needs, by developing ground-breaking monitoring approaches, bridging Signal Processing, Physical Modelling, Artificial Intelligence and Tribology.
Research objectives: The objective of the PATRON project is to develop the next generation of PHM methodologies, algorithms and technologies, so enabling condition monitoring, with the focus on real-time diagnostics and prognostics. This objective will be achieved by having 10 Doctoral Candidates (DCs) working closely and interacting frequently in this inter-disciplinary and multi-disciplinary area. The following sub-objectives have been drawn up to ensure that the objective of PATRON is achieved:
• Novel physics inspired machine learning techniques for condition monitoring of planetary gearboxes
• Novel monitoring indicators linking vibrations with surface topology
• Novel sensing and data analysis techniques based on cameras and fiber optics
• New lubrication quality parameters for monitoring of elastohydrodynamically lubricated contacts
• New boundary layer interface for reduced friction and wear
• New gear contact models including gear cracks and surface pitting propagation
• Novel data driven methodologies for diagnostics and prognostics of planetary gearboxes
• New data driven model for the estimation of the remaining useful life of rotating machinery
• Validation of new prognostics and health management methodologies and technologies for the aerospace, agriculture and general industrial sectors
The above-mentioned objectives will be met through the following activities of the PATRON project:
Bundling knowledge and research activities in the inter/multidisciplinary fields within PHM involved in the various aspects of condition monitoring and maintenance of drivetrains.
Preparing new researchers for challenges ahead in smarter and safer air and land vehicle transport by equipping them with the skills necessary to compete for high-profile positions in industry.
Exposing DCs to the world of engineering in Europe, providing them with the necessary industrial anchoring.
Providing a stimulating and balanced training program to the DCs that includes not just science and engineering, but the important transferrable skills they will need throughout their careers.
Stimulating interactions to match industrial needs with academic research capacity in an exciting training programme for DCs.
Motivating the DCs through research & training that is simply not available to them anywhere else in the world
Promoting the transfer of knowledge between the project’s participants and to disseminate, communicate and exploit the research outputs to the fullest extent.

PATRON is organised in 2 research WPs: WP1: Physics-based & Hybrid Modelling and WP2: Automatic Feature Learning & Decision Making. WP3 focuses in training while WP4 focused on the communication, dissemination and exploitation of the MOIRA results. WP5 takes care of the management running smoothly and via GA meetings and SB meetings, organized twice a year, the project is followed-up closely.
The Individual training programs are adjusted to the needs of the DCs, while all foreseen network wide training courses are taking place.
WP1 focuses in Physics-based & Hybrid Modelling. The main achievements till now are:
• the development of a novel physics inspired machine learning techniques for condition monitoring of (planetary) gearboxes
• the proposal of a new lubrication quality parameters for monitoring of elastohydrodynamically lubricated contacts
• the investigation of a new boundary layer interface for reduced friction and wear
• the development of a new data driven methodology for diagnostics and prognostics of (planetary) gearboxes
• the development of an indicator for severity quantification of defects in drivetrains.
WP2 focuses in Automatic Feature Learning & Decision Making
• the development of compression methods and irregular sampling techniques for vibration signals,
• the integration of explainability into autoencoders for fault detection in planetary gearboxes.
