Abstract :
This paper presents the application of multivariable identification methods to obtain models for commercial road vehicles from measured stress responses arising in certain structural elements due to stochastic road excitation. The elementary subystem representation of the system transfer matrix allowing an effective structure and parameter estimation is used to model the vehicle and noise dynamics. Measurements were carried out on a laminated spring suspension bus, and models were indentified atvarious road profile variances and speed levels of the vehicle.
