Goals

Provide basic notions required for the mechanical design of rotating machines for energy production.

Introduction to the theory of vibrations:

  • Obtain and solve the equations of motion in simple cases and for small (linear) oscillations around equilibrium
  • Understand the concepts of eigenfrequencies and eigenmodes
  • Obtain eigenmodes and eigenfrequencies of discrete systems with n degrees of freedom

Content

1- One efficient method for solving the equations of motion (20h)
Description of the motion of a mechanical system using generalised coordinates
Equations of motion (energy method)
Linearisation of the equations of motion
Free and forced oscillations of a one-degree-of-freedom system
Eigenfrequencies, eigenmodes
Vibration of systems with several degrees of freedom
2- numerical intégration of the equations of motion (8h + 22h practicals)
Deriving eigenfrequencies and eigenmodes for n-DOFs systems
Programming with python

Prerequisites

Basics of mathematics - differential equations, Taylor series, linear algebra
