Experimental consideration of Contact force and Blocked force

Abstract

Transfer path analysis (TPA) has been used as a method for obtaining contribution from multiple vibration sources on the response point. Component TPA is recently proposed TPA method. This method enables us to predict the response point vibration when the input force is changed by employing a virtual force (Blocked force). In this study, we verified the difference between Blocked force and the actual transferred force (Contact force) used in an experimental condition. In addition, we also considered a motor attachment condition where both forces can be applied as almost same.
