Seminar explaining critical points in vibration measurement and analysis that measuring instrument manufacturers and software vendors cannot address
On-demand seminar via Zoom + PDF text
Organizer: Aitop Co., Ltd. Campaign fee: US$700 (all inclusive price)
Vibration measurement and analysis sometimes produce inconsistent results or lead to incorrect conclusions even when performed according to theory or manuals.
This seminar focuses on the “factors that cause incorrect results,” which are not covered in vibration textbooks or manufacturer seminars.
It systematically explains real-world issues such as loss of reproducibility, nonlinearity, misinterpretation of FFT data, and incorrect selection of measuring instruments.
Through this, you will acquire practical skills to correctly interpret measurement results and avoid incorrect judgments.
Do you have any of these problems?
Results are inconsistent even when measuring under the same conditions
Even when looking at FFT results, you are unsure what basis to use for judgment
You are not confident in the results even though you believe you are using measuring instruments correctly
You identify vibration causes but countermeasures do not improve the situation
You cannot explain why measurement results do not match and get stuck in the field
You prefer explanations with minimal mathematics due to difficulty with math, but still want to understand the theory
Target participants
Design, development, and evaluation engineers who perform vibration measurement or FFT analysis but are concerned about reproducibility and reliability
Technicians who can acquire measurement data but struggle with correct interpretation and criteria for frequency analysis and frequency response functions
Field engineers who use measuring instruments but are unsure whether selection and usage are technically appropriate
Practical engineers who cannot improve problems even after identifying vibration causes
Those who want to systematically understand real-world gaps, pitfalls, and technical know-how not covered in manuals or textbooks
Seminar overview
Vibration measurement and analysis often fail to produce consistent results in practice even when performed according to theory or manuals.
This seminar focuses on this phenomenon where “correct procedures still lead to incorrect results,” and systematically organizes the causes. In particular, it explains important practical issues not covered in vibration textbooks, measuring instrument manufacturers, or software vendor seminars.
Explanations are provided with minimal use of mathematics.
・ Fundamental causes of incorrect vibration measurement and analysis results
・ Mechanisms behind loss of reproducibility
・ Correct interpretation of FFT frequency analysis data and common mistakes
・ Influence of differences in measuring instruments and usage methods
・ Systematic explanation of overlooked practical issues such as impact vibration and nonlinearity
