Modal analysis and FEA-test correlation seminar

Event | 14 January 2020 | 8:00 a.m. - 4:30 p.m. EST
Joe Gibbs Racing, 13415 Reese Blvd W, Huntersville, NC 28078

Resonances, mode shapes, MACs, damping?

Modal analysis and FEA-test correlation

Join us for an informative and educational day covering the modal analysis testing and FEA-test correlation on January 14, 2020.

This seminar can help you answer questions such as:

  • 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?

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.
