Experimental review on interior tire-road noise models

Abstract

Exterior and interior tire-road noise is a common problem for car and tire manufactures. Exterior tire-road noise is bounded by UN-ECE R117 and EC R661/2009. Interior tire-road noise on the other hand is determined by market requirements. Since the beginning of the last century different model approaches on exterior and interior tire-road noise have been reported. A brief review of these model approaches is given in order to distinguish which approach to model interior tire-road noise is most promising. Some experimental considerations are given as a guide line for this evaluation. The paper concludes that the most efficient model approach is a full interior tire-road noise consisting of a FEM/BEM exterior tire-road noise model combined with measured structure and air-borne transfer paths
