On friction behavior of rubber on concrete surfaces

摘要

The friction behavior of rubber materials on various contact surfaces is strongly affected by the contact pressure and the relative sliding velocity. Based on a great number of experiments of rubber block moving on concrete surfaces, a friction law is presented in this paper. It is characterized by a dependence on contact pressure and sliding velocity. The identification of the required parameters of this friction law was done by means of a least-square method followed by re-analyses of the experiments. Numerical examples are used to investigate the friction behavior of rubber materials on wet concrete.
