Introduction to mechanical design (UE Polytech'/MI)

This module is a continuation of the HLME303 module and introduces the first analysis tools necessary for the implementation of a design approach for mechanical systems. It aims to give methods of analysis and dimensioning of mechanical systems built on the most widespread technological components.

This module is based solely on lectures and practical work, but maintains a strong interaction with module HLME401 "Technology Project" in order to put into practice all the acquired skills on a case study. Initially, the main methods of modeling mechanical systems (functional analysis, kinematic diagram) will be addressed. Then, we will be interested in the essential technological components used to carry out guidings in rotations (plain bearings) or to transmit power (belt, gear).

• Carry out a functional analysis (interactors diagram and FAST diagram) on an elementary mechanism from 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.), 
• Choose and dimension standard technological components (sliding bearing, gear, epicyclic train).
