Prerequisites

Basics of material resistance and technical drawing.

Main themes
  • Functional analysis of machines and their components
  • Properties of component use
  • Elements of calculus of machine components.
Aims

In consideration of the reference table AA of the program " Master's degree civil engineer mechanics ", this course contributes to the development, to the acquisition and to the evaluation of the following experiences of learning:

  • AA1.1, AA1.2, AA1.3
  • AA2.1, AA2.2, AA2.3
  • AA3.1, AA3.3
  • AA4.1, AA4.2
  • AA5.1, AA5.3, AA5.4, AA5.5, AA5.6
  • AA6.1, AA6.3, AA6.4

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.

Evaluation methods

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
Teaching methods

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.

Content

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
