Case study

This course unit allows students to apply the key steps of a mechanical design process, from the initial specifications to the qualification of the prototype, to one or more concrete cases dealt with in previous years in industrial projects. It thus supports the industrial projects of the year by mobilizing the same skills but on one or more solved cases, unlike the ongoing projects. It therefore requires the application of the various skills acquired in other courses, particularly non-technological ones, at Master's or Bachelor's level (fundamental principles of dynamics, strength of materials, continuum mechanics, vibrations, finite element simulation) to one or more real mechanisms that students can manipulate and experiment with.

• Perform a functional analysis of a mechanical system to be designed based on the initial specifications, characterize (partially) the functions and interactors,
• Formulate and solve a mechanical problem to estimate missing parameters of the system to be designed for preliminary dimensioning and write a calculation note.
• Establish a test protocol to measure mechanical parameters (stiffness, moment of inertia, input-output law in force/moment or speed, etc.).
• Perform a mechanical test, process the data, estimate measurement uncertainties, and write the test report.
• Conduct a creativity FAST,
• Pre-dimension a part of the mechanical system to be designed using a numerical method (e.g., finite elements).

• Fundamental principle of dynamics,
• Strength of materials,
• Mechanics of continuous media,
• Vibration of discrete and continuous systems,
• Finite element method (linear).
