橡胶材料在不同接触面上的摩擦行为受接触压力、相对滑动速度和环境温度的强烈影响。本文在大量橡胶块在混凝土和冰面上运动试验的基础上，提出了三维接触分析的摩擦定律。它的特点是对接触压力、滑动速度和环境温度的依赖性。用最小二乘法对该摩擦定律的参数进行了辨识和修正，并对实验结果进行了重新分析。在橡胶材料摩擦行为的数值研究中给出了几个例子。
The frictional behavior of rubber materials on various contact surfaces is strongly affected by the contact pressure and the relative sliding velocity as well as the environmental temperature. Based on a great number of experiments of rubber blocks moving on concrete and ice surfaces, a friction law for 3D contact analyses is presented in this paper. It is characterized by the dependency on the contact pressure, sliding velocity and the environmental temperature. The identification and correction of the parameters of this friction law were done by means of a least‐square method followed by re‐analyses of the respective experiments. Several examples are given in a numerical investigation of the frictional behavior of rubber materials.
