Efficient and accurate determination of the transfer characteristics of vehicle bodies

  • 27 Accesses

Abstract

An evaluation of the complex properties of the NVH transfer of a vehicle body is done by transfer path analysis (TPA). Result quality is mainly depending on measurement technology and the applied mathematical models. AVL List GmbH developed a new promising approach during a research project and presents the simulation tool TPA-Form, which allows a remarkable increase in efficiency and result quality.
