Modal Analysis and FEA-Test Correlation Seminar

Event | 17 July 2019 8:00 AM PST
Siemens PLM 46871 Bayside Pkwy. Fremont, CA 94538

Resonances, Mode Shapes, MACs, Damping?

Modal Analysis and FEA-Test Correlation

Siemens PLM cordially invites you for an informative and educational day covering the modal analysis testing and FEA-Test correlation on July 17, 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.
