| Abstract: | This article describes the fundamental theory of Transfer Path Analysis(TPA).With the introduction of the latest functions of LMS TPA software tool,the analyzing of structural borne noise or air borne noise contribution to the overall vehicle NVH performance can be done by estimating their operational load and each of their individual FRF.A typical experimental procedure of structural borne TPA is presented in great details for demonstration purpose.The information obtained through this process can be utilized to optimize the NVH performance even the early vehicle design stage. |
