Abstract :
In consideration of the bearing stiffness, the contact deformation between the ball screw and the worktable, and the contact deformation between the worktable and the guide, lateral, longitudinal and torsional vibration of the preload screw and vibration of the worktable are studied. Dynamic model of the ball screw drive system of machines is established using Lagrange equation. The model is analyzed by the mode superposition and Runge-Kutta method and the stability boundaries are plotted. Effects of system´s parameters on stability of the ball-screw drive system are discussed. The present work supplies a base for designing the drive system.
