Abstract

Transfer path analysis (TPA) is a proven method for identifying critical structure-borne and airborne sound paths. The basic idea here is to divide the overall system into an exciting active component (source) and a passive component, e.g., the mechanical structure to be investigated, with their respective measurement points. By separating them, two independent systems are created, whereby on the one hand the excitation behavior can be characterized and on the other hand the transmission behavior can be assessed. Finally, it is checked whether both systems harmonize with each other or whether changes to the source or structure are necessary. The advantage here is the simple description as a black box without complex modeling. In this contribution, this systematic is applied to window regulator systems found in vehicle doors. The focus is on a hybrid approach between experimental and numerical transfer path analysis. For this purpose, the basic workflow of suitable TPA methods is discussed. This includes evaluation of the test rig, the calculation of the contact forces and the numerical analysis of the transfer paths.
