Join ATA Engineering and Siemens to explore the intricacies of structural dynamics and vibration testing. Immerse yourself in a transformative two-day seminar where we delve into the nuances of modal analysis and vibration control. This exclusive, in-person event is your gateway to an enriching experience, offering a platform to connect with likeminded professionals in the testing community.

You are invited to sign up for either one or both days of this free seminar. Our agenda is crafted to deliver valuable insights through theoretical presentations, captivating live demonstrations, and extensive networking opportunities. This event will answer questions like:

• What is fatigue damage? How does one measure damage and replicate it in a test?
• How do random, sine, and shock control work?
• How is a power spectral density calculated?  How is a shock response spectrum calculated?
• How does one identify the natural frequencies and modes of a structure?
• How does one correlate and update modal simulation models?

Don’t miss your chance to join us for this unparalleled exploration of structural dynamics—review the agenda and register below.

Refreshments and lunch will be provided.
