u2.06.41 Dynamic model validation by compute-test correlation

Summary

This documentation is intended to describe the main tools to help validate models in structural dynamics by compute-test correlation. In particular, the following are described:

• how to import data from measurements,

• validation by criteria of MAC,

• validation by comparison of calculated/simulated FRF

• 1. Introduction
• 2. Importing measured data into Code_Aster
  • 2.1. What data should I import?
  • 2.2. Creating an experimental model in Code_Aster
• 3. Model validation by MAC criteria
  • 3.1. What is MAC?
  • 3.2. Field projection
  • 3.3. Calculating MAC between two fashion bases
• 4. Other validation methods
  • 4.1. Validation by visual comparison of modal deformations
  • 4.2. Validation by comparison of FRF
• 5. Appendix
  • 5.1. Unv mesh data set documentation
  • 5.2. Data set reference material 58
  • 5.3. Data set 55 reference material
  • 5.4. Script for the 3D representation of a MAC diagram
