Wajdi Laouini

- Supervise and support a team of 8 engineers involved in 4 different projects for customers such as Alstom, Skoda, HESS, Komatsu... - Distributing the workload and participate in the mechanical solution architecture of the high voltage battery (cells disposition, structure, hydraulic system, sealing…) and validate all outputs (3D models, Drawings) before delivering to customers. - With the company direction, set up the development plans of the team and the training needs.

- Depending on the coupling (series / parallel), define an arrangement of the cells (LTO/NMC) that respects the size of the battery and provides the desired power. - Propose a structure carrying the cells, respect fire resistance, maintainability, water tightness in accordance to the standards in force. - Propose a cooling system which ensures efficient cooling, and the pipe connection and passage. - Define the location of the electrical components and the passage of the cables.

+ Development and design of the chosen solution using the CAD tools (CREO AND INVENTOR). + Making tolerance stack-up analysis GD&T. + Making numerical simulation, static and modal, using CREO-SIMULATE and NASTRAN-IN-CAD. + Making numerical thermal simulations using CRADLE software, and attend meetings with the electronic team to discuss results and location of the electronic components. + Mission of 3 months in Madrid to support the mechanical development department.

+ Editing aircraft certification dossier (frame calculation, panel stringers calculation, specific parts…) for airbus programs A319, A320, A321, A330 and A400M. + Working on SRM calculation (structural repair manual) dossier for A321 program. + Modeling aircraft assembly parts and launch finite element calculation on Patran / Nastran and Hypermesh. + Static and fatigue analysisof nonconformities (concessions) to validate repairs on the structure.

+ Review with customers to define the need and discuss possible solutions. + Design of the final solution on SOLIDWORKS. + Making parts and assembly drawings according to the ISO dimensioning and the internal standards. + Attending meetings with production managers before launching the product in manufacturing. + Follow the product in the manufacturing chain; help the dimensional control and assembly departments.
