Description

In this course the student should acquire the basic knowledge in structural dynamics :

  • Definition and interest of dynamical computation;
  • Classification in terms of lumped, continue and discrete models;
  • Lumped models (n dof) : expression of mechanical transfer functions (impedance, apparent mass etc.);
  • Application to vibration isolation, default identification, parameter identification;
  • Continue models : analytical resolution of beams and plates under dynamical loading;
  • Discrete models (experimental and numerical approach);
  • Experimental modal analysis of discrete models (Eigen frequency, damping, mode shape);
  • Numerical modal analysis of discrete models (implicit and explicit FE approach);
  • Numerical simulation of impact under explicit FE codes.


 

Compétences visées

  • Basic knowlege of mechanical transfer function and understanding of mechanical behaviour;
  • To be able to model a mechanical structure with a lumped model;
  • Capability to conduct an experimental and a numerical modal analysis of a mechanical structure;
  • Simulation of impact phenomenon.
