Correlation between simulations and test on rubber/steel train dampers (Abaqus): - Performing of high distortions 2D & 3D simulations. Most of the simulations in static implicite. A few in dynamic explicite. - Creation of an Excel file to gather all the results of simulations and tests, and to analyse it. - Results analysis: comparison of axial and radial stiffness between simulation and reality; correlation between a fatigue criteria (simulation) and lifespan (test)… Show more Correlation between simulations and test on rubber/steel train dampers (Abaqus): - Performing of high distortions 2D & 3D simulations.

Exoès is a start-up designing heat recovery systems. I worked on the EVE project (Energy Via Exhaust), an axial piston Rankine Expander. It is part of a system intended to create energy from the heat of exhaust gas. - Design and technical drawing of components with Catia V5 (ISO dimensioning). - Dimensioning calculation (bearings, screws, shrink-fit, safety pin...). - Contact with suppliers for the manufacturing of the prototype.

Velan is an international company specialized in the manufacturing of valves for sensitive industries: nuclear, naval, oil and gaz, cryogenics, chemical...A valve's seat must be assembled in the body of the valve with the smaller possible play, to ensure a good water tightness. The dimensions of the seat are therefore grinded after the measurement of the body, to counterbalance a potential machining inaccuracy of the body, which is a complex part to machine. The grinding calculation was… Show more Velan is an international company specialized in the manufacturing of valves for sensitive industries: nuclear, naval, oil and gaz, cryogenics, chemical...A valve's seat must be assembled in the body of the valve with the smaller possible play, to ensure a good water tightness. The dimensions of the seat are therefore grinded after the measurement of the body, to counterbalance a potential machining inaccuracy of the body, which is a complex part to machine. The grinding calculation was previously done manually, and my role was to create the requirements specification to add in the ERP a module to make this calculation automatically. It allows to go directly from the body measurement to the seat grinding, without waiting for the Methods Department to make the calculation, and thus to reduce the production time.During this internship, I had the opportunity to discuss with the operators taking care of the machining and of the metrology, with the IT Department, and of course with the Methods engineers, to find a reliable, feasible, and intuitive solution.
