Aims

Introduce students to basic conceptional notions of machines: functional analysis of machines and their components, properties of use of components, selection of materials, basic dimensioning.

Main themes

- Functional analysis of machines and their components
- Properties of component use
- Elements of calculus of machine components.

Content and teaching methods

First part : functional analysis of machines and their components

- Functional requirements (Specification conditions)
- Principal functions of components (actuation, bearing systems , transmission, …)
- Origin of loads

Second part : properties of component use

- Geometric characteristics
- Tolerances and adjustments, shape tolerances, surface conditions, roughness and scale effects
- Residual stresses

Third part : elements of calculus of machine components

- Dimensioning in relation to elastic limits: calculus criteria, stress concentration, effects of residual stress, safety factors
- Fatigue: dimensioning, calculus methods, residual stress effects
- Current elements calculus

Other information (prerequisite, evaluation (assessment methods), course materials recommended readings, ...)

Prerequisite :
Basics of material resistance and technical drawing

Teaching method :
Parts 1 and 3 are taught via PBL (Problem-Based Learning), followed by synthesizing lectures. Part 2 is taught via lecture courses followed by labs and PBL.

Books can be borrowed from the Science Library.

Grading criteria :
The evaluation is based on work throughout the year (labs and PBL) and on an oral exam session. It includes:
- solving a problem (open book)
- answering a theoretical question
