Fundamentals of vibration testing

Goals

The objectives of the training Fundamentals of vibration testing :

- Raise participants' awareness of realistic and relevant perceptions of different physical orders of magnitude
- Conduct and analyse a test campaign
- Optimise test definition and execution

The aim of the training is to:

• Know how to use physical quantities in the mechanical environment of a structure


• Determine the measurement and test methods according to the programme


• Understand the requirements of test standards


• Participate in the performance of mechanical tests


• Analyse test results

Program

1/ Clarify the fundamentals
Revisit physical quantities and their reality
Review the objectives and parameters used for different types of vibrations: sinusoidal, random, shock, combined, SRC


2/ Identify the right test methods
Interpret the capabilities and performance of the various electrodynamic, electro-hydraulic, shock machines and control systems
Select measurement sensors and their locations
Use appropriate signal processing


3/ Monitor and analyse a test campaign
Define test assembly requirements
Choose the control strategy: basic principles, multipoint strategy and notching
Analyse measurement results based on practical cases


4/ Write a test procedure
Understand the rationale behind the key points of the content
Integrate the constraints and freedoms concerning the order in which the tests are carried out
Carry out a practical application and evaluate your points for attention
