Abstract:
1. A method for outputting a μ-slippage curve for a tire comprising the steps: calculating a friction force between a rubber compound and a rough surface based on a development of a friction coefficient during a contact time and lateral positions of the tire; calculating the friction coefficient depending on a sliding velocity between the rough surface and a tread block and on a temperature of the tire; calculating a motion of the tread block depending on a pressure distribution during movement of the tread block through a contact area and on characteristics of a tire body; calculating effective μ-slippage values for different slippage values based on the friction force and a nominal force; and outputting a μ-slippage curve based on the effective μ-slippage values for different slippage values via an output device.
