CHATTER STABILITY ANALYSIS APPROACH FOR STABILITY ANALYSIS OF ROTATING MACHINERY VIBRATIONS

Yıl 2017, Cilt: 3 Sayı: 1, 1 - 17, 30.06.2017

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.
