Why this seminar?
Vibration Analysis using FEA has become a common engineering practice across all industry verticals. Often, these analyses have to be correlated with test results.Seminar will address some of the ‘issues’ that concern designers and FEA analysts.
Designer’s Issues:
- How to design for appropriate strength and stiffness?
- How do I avoid resonance hotspots in design?
- How do I validate design?
- How to optimize design?
FEA analyst’s Issues:
- How can I verify the FEA models?
- How confident on my FEA results?
- How to get my models correct?
What Happens in the Seminar?
- Lectures and interactions with expert speakers
- Close interaction between peers from other industries
- Hand calculations of vibration analysis
- Quizzes
- Case studies of vibration analysis and correlation; discussion on problems faced during correlation.
Who Should Attend the Seminar?
- Design engineers who want to understand vibration analysis using FEA.
- FEA analysts who want to deepen their knowledge.
- Vibration testing engineers who want to understand how finite element analysis of vibration works.

PREAMBLE
Dynamic Finite Element Analysis (FEA) is essential for both design verification and optimization. It encompasses a range of applications, including routine mode shape and displacement calculations, impact and crash analysis, transient dynamics, and vibration-induced fatigue. FEA analysts perform these analyses to ensure that the design meets its intended functional requirements.
Designers must rely on the results provided by FEA analysts to verify that these requirements are fulfilled. This reliance raises several critical questions that analysts need to address:
- How can we create robust FEA model?
- How best can we capture the physical reality in our FE model?
- How do we validate our FE models using analytical, closed form solutions?
- How to check and control the quality of our Finite element models?
- How do we impose confidence and defend our dynamic FEA report?
- …. And many more
