Abstract

These are many sources vibration during turning operation. One of these vibration is mass unbalance. The excessive vibration will increase rougness and reduce the quality of geometric of product. Therefore, it is necessary to analyze the dynamic behavior of lathe machine. In this study, we analyze the dynamic behavior of lateh machine using ANSYS 11.0 Workbench In this research, principal structures and their material which influence the stiffness of the lathe machine were modeled with help of software Catia V5R14. The lathe machine was modeled in three configuration of tailstock position to determine the FRF. The analysis uses 100 N of excitation force. While mass unbalance with different spindle speed was simulated and compared to normal condition The simulation shows that the biggest displacement response (receptance) was occurred in toolpost with 4.60.10-7 m/N and 88.916 Hz of frequency of resonant. The frequency of critical speed was occurred at 15.923 Hz and 35.764 Hz Keyword : Stiffness, Receptance, Natural Frequency, Resonant Frequency , Frequency Respon Function, mass unbalance, Fast Fourier Transform, Critical speed
