Abstract:
The coupling between experimental and theoretical dynamics of the vehicle occurs already at the level of the recorded vertical accelerations at the centres of the wheels, reflecting the interface between dynamics of vehicle, road and environment. Vertical accelerations measured at the centres of vehicle wheels are, in fact, the state variables of vehicle dynamical system. Vertical acceleration at the wheel centre interlinks with the other state variables and inputs, making a starting point for monitoring the vehicle’s mechanical and functional couplings. This paper reviews possible applications of vertical acceleration records acquired at the wheel centres in consideration of direct couplings between vertical accelerations at the centres of the wheels, spectral analysis of corresponding frequency response functions and couplings with vertical acceleration of vehicle suspension elements. Applications also include indirect determination of vertical wheel loads, vehicle excitation spectra due to road roughness and relative displacements of suspension systems.
