This is an introductory seminar that systematically explains the essence of vibration in rotating machinery from the perspective of “why vibration occurs when rotation happens.”
It organizes the relationship between natural frequency, resonance (critical speed), and rotational order, and clarifies the overall picture of vibration phenomena required in practical engineering.
FFT and waveform data interpretation are explained in connection with rotational speed, enabling participants to learn how to identify causes from measurement results.
Through typical problems such as unbalance and misalignment, participants develop fundamental skills for judgment and cause estimation in real-world situations.
Do you have any of these issues?
- Difficulty understanding vibration behavior specific to rotating systems (relationship with rotational speed)
- Unclear understanding of vibration measurement and analysis (waveforms and FFT)
- Measurements are taken, but data cannot be effectively linked to rotational speed
- Cannot narrow down causes from rotational orders (1X, 2X, etc.)
- Diagnosis and troubleshooting methods vary by person, making decisions inconsistent
Target Participants
- Engineers involved in design and development of rotating machinery and mechanical systems
- Production engineering, manufacturing engineering, maintenance engineers
- Engineers responsible for vibration, noise, and reliability evaluation
- Engineers involved in troubleshooting and root cause investigation
- Young to mid-level engineers seeking systematic learning of vibration fundamentals
Seminar Overview
This introductory technical seminar systematically explains the essence of vibration in rotating machinery from the viewpoint of “why vibration occurs when rotation happens.”
Participants will understand resonance (critical speed) and natural frequency relationships at a practical level and learn correct approaches to vibration source identification.
In addition, typical failure modes such as unbalance and misalignment are organized comparatively, enabling participants to develop the ability to interpret measured data and identify causes.
Through failure case studies, common mistakes in design, development, and production engineering fields are highlighted and avoided.
- Learn fundamentals of vibration phenomena based on the relationship between rotational speed and vibration
- Understand resonance (critical speed) mechanisms and practical considerations
- Learn how to interpret FFT and waveform data in relation to rotational order
- Organize characteristics of typical failure modes such as unbalance and misalignment
- Acquire basic diagnostic thinking for narrowing down causes from measurement data
