Goal(s)

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

Responsible(s)

Barthelemy HARTHONG
