Summary

This course presents advanced mechanical engineering concepts through concrete examples of precision mechanisms. These mechanisms operate in extreme environments, whether in space or on earth. Theoretical concepts are covered in depth, as well as environmental constraints.

Important concepts to start the course

This multidisciplinary course is based on the notions of physics and engineering acquired during the bachelor cycle.

Learning Outcomes

By the end of the course, the student must be able to:

• Formulate functional and environmental requirements based on established specifications.
• Design high-precision mechanisms compatible with the constraints (material compatible with vacuum/radiation, thermal effects, magnetic effect, shocks, vibrations, wear, degassing, emission of particles, etc.) relating to the operating environments.
• Identify the analyzes required in order to carry out the critical sizing of a mechanism.
• Predict the performances of a given mechanism and develop experimental protocols to validate them experimentally.
• Assess / Evaluate the life duration of a mechanism, establish maintenance and dismantling procedures.

Transversal skills

• Use a work methodology appropriate to the task.
• Communicate effectively with professionals from other disciplines.

Teaching methods

Note that the teaching is given in French, but lectures notes are in English, as both master's and bachelor's students can follow the course.
