Abstract:

The ball screw feed system (BSFS) is an important component of numerical control machine tools. The dynamic characteristics of BSFSs directly affect the machining precision and efficiency of machine tools. Due to the external excitation, the feed system can generate large vibrations, which can further decrease the precision of machine tools. This paper designs multiple tuned mass dampers (MTMDs) for the BSFS to reduce the vibration and proposes a dynamical model of a BSFS with MTMDs. The optimization objective is to minimize the maximum amplitudes of the lateral direction direct frequency-response function of the work table at different nut locations. The particle swarm optimization algorithm is used to optimize the stiffness and damping parameters to reach the optimal vibration reduction effect. Furthermore, the MTMDs are adjusted quantitatively to match the optimized dynamic parameters of dampers. By comparing the experimental modal results with and without the damper and the vibration signals during the reciprocating cycle operation, the effect of the damper on controlling system vibrations is verified. The results indicate that the proposed lateral vibration control method for the BSFS can effectively reduce the lateral vibration of the work table in the whole stroke.
