A basic study of damping layout based on structural intensity distribution

Vibration measures can be taken at three main locations: the vibration source, propagating part, and radiating part. However, source are often difficult to implement, countermeasures part inefficient. Therefore, propagation expected. For technique of structural intensity (SI) is used, which effective in understanding path. Then, we attempt reduce by a viscous damper layout based on SI distribution. In this paper, most for reduction presented 2 3 DOF systems. As result, it was found that adding response side effective. beam system, relationship between ratio change velocity also discussed. Based these findings, method identifying location newly proposed, its effectiveness verified.
