In this context, Rolls-Royce Solutions Liège is developing a new generation of its UPS system, the Kinetic Energy Storage System (KESS). In this new architecture, the kinetic accumulator is removed from the main drivetrain. The short-term energy storage function is taken over by a standalone flywheel operating under vacuum with magnetic bearings, which provides a longer ride-through time than the integrated accumulator. The new system consists of a genset comprising an MTU core engine, an electromagnetic clutch, a flywheel and a synchronous alternator, combined with this standalone flywheel energy storage unit. This thesis presents the mechanical design and structural validation of the genset. The flywheel is dimensioned to meet an inertia requirement of 561 kg.m^2 and validated by finite element analysis under three load cases, with a maximum von Mises stress of 234 MPa remaining below the yield strength of S355J2. The taper lock, the electromagnetic clutch and the bearings are selected based on the requirements of the application. The intermediate shafts are dimensioned based on both static and dynamic. The dynamic safety is assessed using ROSS, confirming that the first critical speed at 2253 RPM is safely above the operating speeds. Finally, the housing is validated through an iterative structural and modal analysis. Geometric modifications are applied to meet the structural requirements, and the modal analysis confirms a safety margin of 26.3% on the third axial mode with respect to the operating frequency of 30 Hz Sun, 28 Jun 2026 22:00:00 GMT http://hdl.handle.net/2268.2/26080 2026-06-28T22:00:00Z http://hdl.handle.net/2268.2/26021 Title: Contribution to the Development of a Modular and Adaptable Autonomous Mobile Robot Abstract: This master’s thesis was carried out during an 80-day industrial internship at Cilyx, a Belgian engineering company developing Autonomous Mobile Robots (AMRs) for industrial and pharmaceutical environments. The work contributed to key stages of the development cycle of a first AMR prototype, spanning the initial state of the art, mechanical design, hardware selection, and engineering validation analyses. A structured review of the core technologies underlying AMR operation was first presented, covering localization methods (odometry, sensor fusion, SLAM) and path planning algorithms, including the Elastic Band approach. Based on this analysis, available market solutions were evaluated, leading to the selection of the Siemens SIMOVE platform as the most suitable technology for navigation, fleet management, and safety integration. The hardware architecture was then defined in detail, covering the controller and I/O selection, the driving system based on ArgoDrive omnidirectional motors, the wireless communication infrastructure, the human-machine interface, and the safety systems. A full bill of materials was established for both POC 1 and POC 2. The mechanical design of POC 2 was carried out entirely in SolidWorks, resulting in a compact two-module architecture: a standard lower mobility module common to all future AMR variants, and an interchangeable upper module adaptable to client-specific requirements. Disassembly and maintainability were explicitly considered during the design phase. A set of engineering analyses was conducted to validate the design: static structural simulations confirmed mechanical integrity under the applied load cases; a parametric stability analysis tool was developed to evaluate tipping risk during cobot motion and base displacement; and parametric energy and thermal models were built to facilitate reuse by Cilyx engineers for future configurations. Finally, the applicable regulatory framework was reviewed, covering ISO, IEC, GMP, and pharmaceutical standards, as well as the specific requirements expressed by the targeted client environments. This regulatory mapping provides Cilyx with a structured basis for the certification process of future AMR deployments.

Une approche intégrée combinant modélisation, simulation et optimisation est développée à partir de données industrielles réelles. Un simulateur Python réaliste est conçu pour représenter le convoyeur, les robots, les bacs, les soufflettes et les flux de pièces, puis validé expérimentalement. L’analyse met en évidence plusieurs sources de pertes, notamment la surcharge des robots, les contraintes cinématiques et les stratégies de sélection des pièces. Le cœur du travail repose sur l’optimisation de l’ordre des bacs par robot via une fonction objectif économique intégrant rendement, temps de cycle et pénalités de pollution. Des améliorations complémentaires, comme l’optimisation des soufflettes et l’homogénéisation du flux amont, sont également étudiées.
