Abstract
This paper describes the damping loss factor estimation method of the statistical energy analysis (SEA) using the Power Injection Method (PIM). The parameter called loss factor in SEA is estimated by PIM. However, PIM is necessary to measure the vibration in a lot of points. Moreover, if the structure of subsystem is changed, the parameter needs to be estimated again. In this study, the influence that the difference of measurement points gave the analytical result was verified. Furthermore, we proposed the estimation method of damping loss factor on subsystem which was fitted rubber by using experimental results of attached element.
