Recently, mechanical noise and vibration problems, including automobile and product development, came to be regarded as a differentiating factor between competing products and they are becoming more important issue. Especially in the automotive development process for this issue, pathway analysis (Transfer Path Analysis below, TPA) has been analyzed. This is a technique to identify the contribution from more than one source of vibration. In order to make the product of low noise and low vibration and shorten the process, this is required high accuracy and efficiency. In this study, analysis focused on the contribution of each vibration excitation force identification and pathway analysis using the inverse method, validation and accuracy of the theory is examined. The regular-inverse matrix method, and the pseudo-inverse matrix method are compared. The former is for the case of same number of excitation and response points, and the later is for the case of increasing the number of response points.
