This seminar systematically explains a rational design method for ensuring the intended vibration reduction effect by properly applying damping, rather than simply “adding damping.”
It organizes practical decision-making points such as how to determine damping levels, evaluation methods, and damper placement.
It also covers applications to not only translational vibration but also rotating machinery and torsional vibration, as well as appropriate use cases for dynamic vibration absorbers.
The seminar clarifies the difference between “effective damping” and “ineffective damping,” enabling participants to design efficient vibration countermeasures without waste.
Do you have these issues?
- Even after adding damping, vibration does not decrease as expected
- You are unsure how much damping should be applied
- You are not confident in damper selection or placement
- Countermeasures for rotating machinery or torsional vibration are uncertain
- You cannot decide whether to use a dynamic vibration absorber
Seminar Overview
Damping is not something that simply “should be added”; it is ineffective unless properly designed. This seminar explains the fundamental concept of damping and organizes practical evaluation methods and design procedures in a clear manner. It also covers applications to rotational and torsional vibration, as well as the use of dynamic vibration absorbers, in a form that can be directly applied to engineering practice.
・ Basic concepts for effectively applying damping
・ How to determine damping levels and key evaluation points
・ Damper selection and placement strategy
・ Methods for addressing rotating machinery and torsional vibration
・ Basic design and usage of dynamic vibration absorbers

Main Outcomes of This Seminar
- You will move away from trial-and-error damping application and be able to determine damping levels, damper placement, and application methods based on solid engineering rationale, achieving efficient and targeted vibration reduction.
- You will be able to design damping systems not only for translational vibration but also for rotating machinery and torsional vibration, and independently decide and design vibration countermeasures including the use of dynamic vibration absorbers.
Required Background Knowledge
- Basic university-level mathematics and mechanics knowledge is desirable; however, even without it, the essential concepts and key points will be explained carefully so they can be understood.
