This seminar systematically organizes experimental modal analysis, operational modal analysis, and the finite element method, and theoretically clarifies the causes of discrepancies in results encountered in practice.
From frequency response function (FRF) measurement to MAC evaluation and model updating, the content is systematically organized to develop correct interpretation skills for analysis results.
Furthermore, it explains practical evaluation methods and feedback approaches to design for bridging the gap between experiment and analysis.
It strengthens practical decision-making skills to connect vibration problems from “phenomenon understanding” to “design improvement”.
Do you have these problems?
- You perform experimental modal analysis but are not confident in interpreting results
- You are not sure whether your FRF measurement method is appropriate
- Experimental modal analysis results do not match finite element analysis
- You do not know how to evaluate correlation analysis (MAC) results
- You do not know the theoretically correct way to use sensitivity analysis and structural modification simulation
Seminar Overview
In this seminar, experimental modal analysis, operational modal analysis, and the finite element method (FEM) are treated in an integrated manner, and the fundamental causes of the frequently occurring “discrepancy between analysis results” in practice are explained from both theoretical and practical perspectives.
From frequency response function (FRF) measurement to modal analysis, MAC evaluation, and model updating, the content is systematically organized to develop practical skills for correctly interpreting analysis results and applying them to design.
- Organization of relationships among experimental modal analysis, operational modal analysis, and finite element method
- Correct measurement and evaluation concepts of FRF (frequency response function)
- Systematic methods for identifying causes of mismatched analysis results
- Correct evaluation methods of modal correlation using MAC
- Model updating and concrete approaches to design improvement

Key Outcomes of This Seminar
- Even when experimental modal analysis and finite element analysis do not match, you will be able to technically identify causes and correct them to obtain valid evaluation results.
- Based on FRF, mode shapes, and MAC results, you will be able to determine priorities for structural modification and model correction, and connect vibration problems directly to design improvement.
