Introduction to Mechanical Design (Polytech'/MI)

This module follows on from module HLME303 and introduces the initial analysis tools required to implement a mechanical systems design approach. It aims to provide methods for analyzing and dimensioning mechanical systems built using the most common technological components. 

This module is based solely on lectures and tutorials, but maintains a strong interaction with the HLME401 "Technology Project" module in order to put all the skills acquired into practice in a case study. Initially, the main methods of modeling mechanical systems (functional analysis, kinematic diagram) will be covered. Then, we will focus on the essential technological components used to achieve rotational guidance (plain bearings) or power transmission (belts, gears).

• Conduct a functional analysis (interactor diagram and FAST diagram) on a basic mechanism based on the manufacturer's plans and documents.
• Construct the kinematic diagram of a 2D or 3D mechanism from the general layout plan. 
• Analyze a power transmission chain and calculate the associated characteristics (transmission ratio, efficiency, etc.). 
• Select and size standard technological components (plain bearings, gears, planetary gear trains).
