In this seminar, we systematically explain the theory and practical judgment skills necessary to properly utilize finite element vibration analysis in real-world applications.
In particular, we focus on clarifying the causes of discrepancies between analysis results and experimental modal analysis results, and on specific methods to improve correlation accuracy.
From the fundamental understanding of eigenvalue analysis to damping settings, modeling techniques, and frequency response analysis, everything is organized in an integrated manner for direct practical use.
Furthermore, through evaluation of analysis validity and application to design decisions, the goal is to acquire truly usable analytical skills.
Do you have these problems?
- You do not understand why analysis results do not match experiments
- You do not know how to set damping correctly
- You cannot identify the root cause of a problem even after analysis
- You do not understand what the analysis software is actually calculating
- You cannot explain analysis results to supervisors or clients
Seminar Overview
This seminar systematically explains the knowledge and judgment skills necessary to properly utilize finite element vibration analysis in practical engineering work.
Starting from a fundamental understanding of eigenvalue analysis, it covers finite element modeling, damping treatment, and frequency response analysis in a consistent manner.
In addition, it explains how to interpret modes and apply them to design, and how to compare them with experimental modal analysis, enabling participants to evaluate and connect analysis results to real machines.
- Understanding the basic principles and practical meaning of finite element vibration analysis
- Correct use and interpretation of eigenvalue and frequency response analysis
- Practical methods to improve correlation with experimental modal analysis
- Modeling techniques for damping, boundary conditions, and contact conditions
- Evaluation and utilization methods to apply analysis results to design decisions
