Wael Masmoudi is a material engineer who graduated from the National Engineering School of Sfax in 2019. After finishing his MITACS Globalink Internship at I2E3 (Innovations Institute in Eco materials, Eco-products, and Eco-energies) of the Québec University of Trois-Rivières (Canada) where he worked on the characterization of natural fibre composite quasi-isotropic laminates. He was also involved in multiple projects in the field of structure lightening and optimization such as the design and manufacturing of a carbon fibre reinforced epoxy monocoque of an ecological car for participating in the Shell Eco-marathon competition in London 2018. He has been involved, as a mechanical engineer, in several industrial projects with companies like SOPAL and SKG.
Through the ESR project, Wael aims to improve his skills in the field of structure lightening and to acquire a better understanding of structural dynamics and vibroacoustic under the supervision of a highly qualified professional and academic network that will lead him to take a major step forward in his career.
The main goal of this ESR is the definition of the best procedures to reduce weight of transmission components (gears, shafts and bearings) using new lightweight materials. The use of composite materials of different properties will be addressed among other possible materials. The impacts of the material properties on the NVH and efficiency aspects of the transmission will be completely considered. The transmission error behaviour when lightweight materials are used is one important property. The associatedwhining noise will be assessed in order to proceed with the optimisation. The research will have to deal with numerical methods and parametric survey analysis. The inputs needed for this ESR are: industrial and manufacturing constraints of the standard gearbox geometries and characteristics. Finite Element Method models of existinggearboxes will be used for optimization.
