Simulation of deterministic tyre noise based on a monopole substitution model

Abstract This paper deals with tyre noise indoor tests in a semi-anechoic chamber and with the identification of a monopole substitution model suitable for simulating the deterministic part of the sound field generated by a rolling tyre. The first part of the paper illustrates the test procedure and the data processing methodology adopted for separating the deterministic contribution to tyre noise, i.e. that mainly related to tread pattern, from the random one. In the second part, the monopole substitution model is presented, together with the results of model identification and sound field simulation. The results reported in the paper for two commercial tyres (with the same size and similar structural characteristics, but with different tread pattern design) show how the predominance of the deterministic/random noise contributions varies with frequency and confirm the random noise spectrum to be substantially independent of the specific tread pattern. With reference to the monopole substitution model, its capability of reproducing the acoustic field radiated by a rolling tyre is assessed through the analysis of both sound spectra and space distribution.
