“…A series of sequential measurements over the whole tire structure is used to calculate the operational modal parameters of the rotating tire. The conclusions from those tests and analyses are valid for both smooth as profiled tires because below 500 Hz, the structural behavior of a tire is determined by the tire construction and is independent of the tread profile [5].…”

“…The changing surface geometry caused by the tread elements makes it impossible to focus the laser beam at the tire surface. Saemann et al [5] developed an indirect measurement method, which can also be used on profiled tires, based on sound pressure measurements. A microphone array is placed around the rotating tire.…”

“…The time-domain procedure can also be employed for out-of-plane tests, while passing-over-cleat under an angle [32]. Excitation of a loaded car tyre with shaker is carried out in [33], the focus being again on inplane modes for NVH investigations. Both impulsive and shaker excitations are considered in [34], with a discussion on the common issues faced when testing tyres.…”

An experimental procedure for the identification of the dynamic parameters for the rigid-ring tyre model

et al. 2023

Several approaches have been developed over the years for the modelling of the tyre behaviour in vehicle-dynamic applications. The so-called ‘rigid-ring’ models are among the classics for the modelling of the belt dynamics. Although there are several works dealing with the vibrating properties of tyres, the problem of the identification of the related rigid-ring model parameters has not been described other than qualitatively or partially. The aim of this work is thus to fill this gap and to devise a procedure for the experimental characterisation of such parameters, namely the frequency and damping of the in-plane and out-of-plane belt vibration modes as well as the associated masses and inertias. An experimental modal analysis (EMA) approach is employed, which involves an instrumented hammer combined with three-axial accelerometers roving on 16 stations equally spaced along the tyre circumference. The method is numerically demonstrated on the finite-element models of a motorcycle tyre and a car tyre. The approach is also experimentally validated on a real tyre. The rigid-ring vibration modes of the motorcycle tyre are in the range 70–220 Hz, while those of the car tyre are in the range 51–85 Hz. The ratios of the mass/inertia of the rigid ring to the mass/inertia of the tyre are in the range 40–87% and 68–74% for the motorcycle and car respectively.
