Vibratory diagnosis

Training course in vibratory diagnosis of rotating machines

VD Training course – Second-level vibratory diagnosis, using advanced techniques
The second-level diagnosis analyses the dynamic behaviour of the shaft line during speed and load increase phases. Measuring the shafts’ and bearings’ natural frequencies makes it possible to supplement the diagnosis.

  • Internal vibrations and forces : transfer function, natural frequency and mode, resonance
  • Shock theory
  • In-depth analysis of the dynamic manifestations of the various faults
  • Advanced signal processing techniques applied to second-level diagnosis
  • Analysis of transient regimes: speed, load
  • Diagnosis methodology

Interactive case studies

Industrial case studies are put to the participants. The latter will have to establish an approach leading to the diagnosis of the problem posed. The participants can bring along their own case studies if they wish.

Staff in charge of vibratory analyses who wish learn more about these diagnoses. Method, reliability.

  • Pre-requisite: Vi course
  • Conduct a second-level diagnosis by using advanced analysis methods
  • Specific application for machines with complex kinematics or slow speed
  • Taking into account the interactions of the vibratory behaviour of the machine with its passive environment (structure) and active environment (process)


  • Practical work on model
  • Case studies on machines from your processes

Course duration: 4 days. 
The practical work can be carried out on your stock of machines during the training in the company. ?
