In this paper, the ball screw feed drive system issimulated and it?s frequency response is studied. Variousparameters effect on the dynamic behavior of the ballscrew system have been investigated. Ball screw feed drivesystem is used in high speed machine tools due to theirhigh efficiency. Estimation of the dynamic behavior of ballscrew feed drive mechanism is very important in theindustrial processes in order to get high demand forprecision and accuracy in machine tools. Optimizing thedrive operation can provide significant cost savings. A fourdegree of freedom system, lumped parameter model isused for modeling a single axis ball screw feed drivesystem and use it to study and analyze vibrations in thismodel. The mathematical modeling provides an importantinformation about frequency response when applyingdifferent levels of table mass, stiffness of the nut, axialstiffness of the ball screw shaft and torsional stiffness ofthe ball screw on the system, to describe the effects of theseparameters on the system dynamic behavior. The study ofdynamic response of ball screw feed drive system providesa better performance control and better understanding ofball screw dynamics.
