Abstract
Transfer Path Analysis has well established in order to improve the noise and vibration quality of mechanical structures. However, the identification of input force is still difficult problem to solve and its accuracy has to be evaluated. This paper presents the evaluation method for the input identification error. In this study, traditional identification method based on accelerance matrix inversion is utilized. The identification error is estimated by evaluating variance of identified force spectra. Then, proposed methods are certified using FEM simulation and experimental approach.
