Generally, the friction force is considered as a constant value. However, it has been shown that the friction force depends on the displacement and shows hysteresis loop in the region of the initial rolling displacement. Hence, it needs to consider the friction force depends on the displacement when dealing with the realistic problems. In this study, we use a curve of the starting rolling displacement, which consider the region of the initial rolling that the rolling friction force depends on the displacement, and make an analysis of the vibration of a one degree of freedom system with the rolling friction. In the numerical analysis, the stop motion is generated in the condition below the resonance point. Meanwhile, it is clarified that the stop motion is almost not generated and the vibration wave shows a sine wave clearly in the condition more than the resonance point. The parameter m that shows the loss energy of a system in a curve of the starting rolling displacement greatly affects the vibration characteristics, and the different characteristics appear in the case of m≧2 or m<2.
