| Abstract/Summary |
A half-car model is used to investigate the dynamic response of cars with uncertainty under random road input excitations in this paper. The mass of the vehicle body, mass moment of
inertia of the vehicle body, masses of the front/rear wheels, damping coefficients and spring stiffness of front/rear suspensions, distances of the front/rear suspension locations to the centre of
gravity of the vehicle body and the stiffness of front/rear tires are considered as random variables. The road irregularity is considered a Gaussian random process and modeled by means of a simple
exponential power spectral density. The mean value and standard deviation of the vehicles natural frequencies and mean square value of vehicles random response are obtained by using the
Monte-Carlo simulation method. The influences of the randomness of the vehicles parameters on the vehicles dynamic characteristic and response are investigated in detail using a practical
example.
