Abstract

The phenomenon of vibrations in the machining and turning process of engineering parts is one of the common problems in the industry that has a significant impact on the surface quality of machined parts, mainly in parts with small thickness and long length. In this study, the effect of applying axial force to the part under the turning process is investigated as a solution to reduce the effect of the vibrations phenomenon. For this aim, the part is modeled as a clamped-hinged beam and the turning tool is modeled as a moving harmonic load. According to the Rayleigh theory, the beam motion equation is extracted. Then, using the Galerkin method, the equation of motion is solved and the natural frequencies and dynamic response of the beam are obtained. To validate the results, the deflection at the midpoint of the beam in the present model is compared with the results of the COMSOL software. The results indicate a good agreement of the numerical results with the COMSOL modeling results. The results show that the axial force, amplitude, and speed of the harmonic force have a great effect on the natural frequencies, maximum deflection, and frequency responses of the beam, such that with increasing axial force, the maximum displacement and frequency response of the beam decrease and the natural frequencies increase. These changes indicate the positive effect of applying axial force in reducing the vibration of the beam.
