Abstract

When two bodies slide on each other the asperities are engaged and friction is created. By superposing ULTRASONIC VIBRATIONS to one of the bodies, the friction force is reduced .This phenomenon is widely used in metal forming and metal cutting. In this research, EXPERIMENTAL STUDY of the effect of ULTRASONIC VIBRATIONS has been on SLIDING FRICTION FORCE in longitudinal direction. For this purpose, set-up was designed and fabricated. The main components of the setup, including generators, transducers, first engaged body and second engaged body. The Set-up was installed on the machine lathe for investigation of the effect of ULTRASONIC VIBRATIONS on SLIDING FRICTION FORCE in longitudinal direction. The experiments were performed for eight different performance conditions. Next, the effect of each parameter ultrasonic wave velocity, roughness and material of contact surfaces were studied on the reduction of the friction force due to addition of ULTRASONIC VIBRATIONS. The result show that range of reduction friction force due to addition of ULTRASONIC VIBRATIONS in longitudinal direction is between 40 to 100% for the different performance conditions ; also, friction force significantly reduced by increasing ultrasonic wave velocity so that friction force can be brought to zero by significant increase in ultrasonic wave velocity. The results also show that friction force has a greater reduction for the surface that has less roughness. Aluminum-aluminum surfaces can acheivereduction friction force from aluminum - steel surfaces.
