Summary:

The paper discusses the identification of multivariable models for air suspension bus structures using the measured stress response arising from stochastic road profile excitation. The vehicle and noise transfer matrices are identified from the time history of measured data. Applying a special parametrization of the transfer matrices, the modal characteristics can also be directly computed. Models were identified at various selected road categories, road profile variances and speed levels, thus the random vibration analysis of the vehicle can be performed for the whole range of operation. The identified models can be used to determine the global dynamic characteristics of the vehicle for arbitrary road profile excitations and speed levels within the examined range
