What is the difference between Dynamic Vibration Absorber (DVA) and Tuned Mass Damper (TMD)? It is quite confusing me some text books are telling they are same and some other telling they are different. Please clear my doubt.
I think
DVA is like absorber in cycle, there is no need of damping, even though it is absorbing vibration. DVA also have damping available in vehicle form bike to car, but TMD damping is needed and its absobing harmonic vibration effectively.
Sir, Thank you for your time and the information. You are right, the usage of name may get changed based on the application but functionality point of view both are similar.
They are almost the same. Though, usually it is called absorber when a spring- damper configuration acts as a ansorber.
