THE CALCULATION OF THE VIBRATIONS OF A FOUR-WHEELED VEHICLE INDUCED BY RANDOM ROAD ROUGHNESS OF THE LEFT AND RIGHT TACK

When applying the known power spectra of the random road roughness to the suspension behaviour of a four-wheeled vehicle, each of the four vertical input signals together with their related interdependence are to be considered, if exact results are to be obtained. The correlations are determined by way of calculation. The resulting roughness spectra of bounce, pitch, roll and torsional excitations will be applied to various vehicles, characterized by different design parameters. By means of a three-dimensional simulation model the virtual values of the random vehicle vibrations are calculated, while determining at the same time the influence of vehicle speed, waviness exponent, track width, wheel base and axle design feature as well as the relationship between the vertical vibrations and the reference point in the vehicle body.(a) /TRRL/
