The damped vibration of a system with a contact surface has been analyzed by considering an occurrence of micro-slip and residual displacement ant the contact surface. The damping characteristics of an oscillatory system have been investigated by clarifying the relationships between the logarithmic decrement and the amplitude, the angular frequency and the amplitude. From the calculated results, it has been clarified that the logarithmic decrement depends on the amplitude, and that it takes a maximum value on a certain amplitude. Furthermore, in case of the existence of a linear spring parallel to the contact surface, the logarithmic decrement reduces with the increasing strength of the linear spring. The angular frequency for the larger amplitude shows close agreement with the value decided by a linear spring. However, in the region of the tangential micro-displacement, it depends on the amplitude and increases with decreasing amplitude.
