CHATTER STABILITY ANALYSIS APPROACH FOR STABILITY ANALYSIS OF ROTATING MACHINERY VIBRATIONS
Journal Title: Kırklareli Üniversitesi Mühendislik ve Fen Bilimleri Dergisi - Year 2017, Vol 3, Issue 1
Abstract
Vibration caused by mass imbalance is an important factor limiting the performance and fatigue life of the rotating system. Therefore, a balancing procedure is necessary for rotating systems. Spindle is the main mechanical component in machining centers. Its performance has a direct impact on the machining productivity and surface quality of the workpiece. In this paper, regenerative chatter analysis approach is used for vibrations of rigid rotors with a massless elastic shaft. This approach is firstly applied in literature by this study. In this study, Stability Lobe Diagram (SLD) is plotted the boundary between stable and unstable rotations as a function of spindle speed and imbalance mass. SLD process can be easily applied between spindle length, balancing mass amount, location of balancing mass on rotor etc. variable parameters and spindle speeds for stable rotating system
