Random Vehicle Vibrations as Effected by Dry Friction in Wheel Suspensions

SUMMARY The changes of vibration comfort and stability of vehicles as effected by the value of frictional force generated in laminated springs are discussed and the probability of departure of the tyres from the ground is described. A partly automated analogue computer simulation being equivalent to a great number of highway experiments was applied in the study. The computer model was excited by several stochastic roadprofile - analogue signals generated by filters from the wide-band random signal of a digital noise generator.
