ゴム材料のしゅう動面に生じる局所的な摩擦振動が摩擦係数に及ぼす影響

A new technology for tuning friction coefficient between rubber and rough surfaces is developed based on friction-induced vibrations occurring in the contact interface. Specifically, we demonstrated that the use of soft rubber film containing hard particles is effective to increase the friction force. In addition, to discuss the mechanism of this friction increasing effect, ‘Tomlinson model’, which describes the energy dissipation due to the jumping of a point subjected to a periodic potential, was introduced. In this study, based on the numerical results of Tomlinson model simulation and some experiments, we discussed the effect of two parameters, i.e., Young’s modules of the soft rubber film and vertical load, on the friction coefficient.
