PARAMETRIC INVESTIGATION OF THE HARMONIC VIBRATIONS OF GEARBOX FOR LATHE MACHINE OPERATION

This study reports the possibility of determining the reliability of the Lathe machine in the turning process using vibration analysis. The machine gear train was modeled in SolidWorks and modal analysis was used to determine the vibration characteristics of the lathe machine gearbox, by determining the mode shapes and natural frequencies. The dynamic response of the system was obtained from harmonic analysis using ANSYS. The system s stiffness, mass, and damping parameters were obtained from the analyses. The first six natural frequencies were obtained between the range of 0-800 Hz. The six mode shapes were obtained at various natural frequencies and maximum deformation of 432.91 Hz, 402.52 mm , 482.75 Hz, 428.98 mm , 507.83 Hz, 526.07 mm , 544.16 Hz, 445.71 mm , 671.98 Hz, 944.32 mm , 735.11 Hz, 856.58 mm . The modal analysis showed that the system natural frequency is greater in the 6thmode. The system s resonance frequency occurs at 126.01 dB at a natural frequency of 479.89 Hz. The resonance magnitude of the system limits the operating frequencies of the machine above which the system is considered not reliable for safe operation.
