INVESTIGATIONS ON THE SIDE SLIP BEHAVIOR OF PLASTIC TIRES

The present paper reports for the first time experimental results of t he measurement of steady state side slip effects of plastic tyres comm only used for ground floor industrial vehicles. Two different types of lyres, one steering lyre and one tyre of the load wheel have been exa mined on a tyre testing rig by measuring the lateral force for differe nt side slip angles. Additionally the influence of the rolling speed a nd of the wheel load has been taken into account The resulting steady state side slip characteristics of the plastic lyres quantitatively lo oks like the characteristic of conventional pneumatic tyres. In contra st to the wheel load the rolling speed has no significant influence. B ased on this result the dynamic behaviour of industrial vehicles can b e examined using linear or nonlinear models for which it is useful to expend the presented analytical approximation of the measured characte ristics.
