Modal Analysis and FEA-Test Correlation Seminar

Event | 23 July 2019 10:00 AM GMT
Siemens Industry | 100 Technology Drive | Alpharetta, GA 30005

Resonances, Mode Shapes, MACs, Damping?

Siemens PLM cordially invites you for an informative and educational day covering the modal analysis testing and FEA-Test correlation on July 23, 2019.

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?

Live demonstrations will be given throughout to help reinforce the topics.
