Introduction to mechanical design (UE Polytech'/MI)

This module is a continuation of the HLME303 module, and introduces the initial analysis tools needed to implement a design approach for mechanical systems. It aims to provide methods for analyzing and dimensioning mechanical systems built on the most widely used technological components.

This module is based solely on lectures and practical work, but maintains a strong interaction with the HLME401 "Technology Project" module, in order to put all the skills acquired into practice on a case study. Initially, the main methods for modeling mechanical systems (functional analysis, kinematic diagrams) will be covered. Then, we'll look at the essential technological components used to guide rotation (plain bearings) or transmit power (belts, gears).

• Perform a functional analysis (interactors diagram and FAST diagram) on an elementary mechanism using the manufacturer's drawings and documents,
• Construct the kinematic diagram of a 2D or 3D mechanism from the overall drawing, 
• Analyze a power transmission chain and calculate the associated characteristics (transmission ratio, efficiency, etc.), 
• Select and size standard technological components (plain bearings, gears, planetary gears).
