摘要： A method for calculating a μ-slippage curve for a tire based on laboratory data derived from characteristic values of a used compound, of the road surface and a vehicle without producing a complete tire, and a method for calculating a μ-slippage curve for a tire include the steps: calculating a friction force between rubber compound and a rough surface based on a friction coefficient for different slippage values and lateral positions of the tire wherein the friction coefficient is calculated depending on a sliding velocity between the rough surface and a tread block and on a temperature of the tire. After calculating the friction force, the motion of a tread block depending on pressure distribution during the movement of the tread block through the contact area and on characteristics of a tire body is calculated. The resulting μ-slippage curve is composed from effective μ-slippage values for different slippage values wherein effective μ-slippage values are calculated based on the friction force and a nominal force derived from the pressure distribution.

摘要： A process for producing a vulcanizable rubber composition containing silica and carbon black, comprises the step of intimately mixing at a temperature of from 130° to 180° C. at least a first cross-linkable unsaturated chain polymer with a first carbon black-based reinforcing filler, so as to obtain a first rubber composition capable of allowing a subsequent effective dispersion of a second silica-based reinforcing filler and of a second cross-linkable unsaturated chain polymer. The rubber composition thus obtained shows a homogeneous dispersion of the reinforcing fillers, in particular of the silica-based reinforcing filler, constant physical-mechanical characteristics, and improved drawability, and is particularly suitable for the manufacture of tire treads with low rolling resistance.
