Modal Analysis and FEA-Test Correlation Seminar

We invite you to join us for an informative and educational day covering the basics of Modal Analysis and FEA-Test Correlation on Wednesday, April 18, 2018 in Pittsburgh, PA.

This seminar can help you answer questions like:

• What is modal analysis? Why are resonant frequencies important?
• How can I prove that my simulation model is accurate? How can I get realistic damping?
• What is the significance of frequency response functions (FRFs) and how can they help me?
• What is the Modal Assurance Criterion, and what role does it play?

This seminar is designed for anyone who wants to learn how to perform modal analysis. Live demonstrations will be given throughout to help reinforce the topics.

In this free seminar, both simulation and test software will be presented, as well as a live demonstration of modal testing.
