In this paper, the ball screw feed drive system is
simulated and it?s frequency response is studied. Various
parameters effect on the dynamic behavior of the ball
screw system have been investigated. Ball screw feed drive
system is used in high speed machine tools due to their
high efficiency. Estimation of the dynamic behavior of ball
screw feed drive mechanism is very important in the
industrial processes in order to get high demand for
precision and accuracy in machine tools. Optimizing the
drive operation can provide significant cost savings. A four
degree of freedom system, lumped parameter model is
used for modeling a single axis ball screw feed drive
system and use it to study and analyze vibrations in this
model. The mathematical modeling provides an important
information about frequency response when applying
different levels of table mass, stiffness of the nut, axial
stiffness of the ball screw shaft and torsional stiffness of
the ball screw on the system, to describe the effects of these
parameters on the system dynamic behavior. The study of
dynamic response of ball screw feed drive system provides
a better performance control and better understanding of
ball screw dynamics.
