In this paper, the reduction of sliding friction by ultrasonic vibration parallel to the sliding direction has been studied. Relation between a relative sliding velocity in a contact surface, and a coefficient of dynamic friction is analyzed by the finite element methods. The analytical solutions agrees well with a theoretical solution, and it can't be based on a material physical properties value. Stress also decreased with reduction of a coefficient of dynamic friction. The work of the sliding loss in a contact surface is calculated, and it compared with the theoretical solution. With the increase in the amplitude of ultrasonic vibration, the increase in the heat quantity of a contact surface is confirmed.
