The aim of this transfer centre is the determination of material parameters for interface models describing the dry and wet friction of rolling tires. The research programme includes:(1) Selection of a class of friction equations with hierarchical order for the rolling contact between tires and dry roadway (concrete or asphalt).(2) Identification of the material parameters based on experimental data taking into account the inhomogenities of the specimen; sensitivity analysis for 2D-systems.(3) Numerical stress analysis of rubber blocks in a linear friction test unit and in the Grosch abrader test unit, respectively.(4) Verification of the friction model with selected experimental data for stationary rolling tires by complete friction contact analysis of the 3D-systems.(5) Consideration of uncertainties.(6) Selection of a class of friction models with seperated terms for adhesion and hysteresis; identification of the material parameters under consideration of additional input parameters (e.g. wet roadway).

该传输中心的目的是确定用于描述滚动轮胎的干摩擦和湿摩擦的界面模型的材料参数。研究内容包括：（1）轮胎与干路面（混凝土或沥青）滚动接触摩擦方程的选择。(2)根据实验数据识别材料参数，同时考虑试样的不均匀性; 2D系统的灵敏度分析。(3)分别对线性摩擦试验装置和Grosch研磨机试验装置中的橡胶块进行数值应力分析。(4)通过对3D系统进行完整的摩擦接触分析，用选定的固定滚动轮胎的实验数据验证摩擦模型。(5)考虑不确定性。(6)选择一类带有附着力和滞后分离项的摩擦模型;在考虑额外输入参数（例如湿路面）的情况下识别材料参数。
