The task of modelling tyre noise and vibration is complicated by the need to simulate the rolling process in the time domain. Conventionally, the calculation employs a convolution-integral formulation, which can be numerically demanding. This paper describes an alternative approach, based on a state-space representation. The latter is obtained via frequency-domain-based system-identification techniques, applied to linear models of the tyre structure and tread rubber. The resulting time-domain simulation has low computational demands, and predicts belt accelerations that are in reasonable agreement with data measured on a rolling-drum test rig. The method thus constitutes a viable alternative to the convolution-integral approach, and warrants further development.
