LMS cordially invites you to join us for an informative and educational day covering the fundamentals of structural dynamics testing and Digital Signal Processing.
This free seminar can help you answer questions like:
-
What is modal analysis? Why are resonant frequencies important?
- How can I accelerate my tests without inducing modes of failure not found in the field?
-
What is the significance of Frequency Response Functions (FRFs) and how can they help me?
-
How do I tranform data from the time domain to the frequency domain?
-
How do I select an appropriate sample rate?
-
How do digital filters work?
-
What is aliasing and leakage?
This seminar is designed for anyone who wants to learn about structural testing and how to more effectively resolve dynamic issues.
Live demonstrations will be given throughout the day to help reinforce the topics and provide practical insight for those new to this type of testing and analysis.
In this free seminar, both
simulation and
test methods for better acoustic engineering will be presented in an interactive, side-by-side format.
