Abstract:

With the change of the wall thickness in the milling process, the vibration of a thin-walled workpiece is of obvious time-varying characteristics. To realize the effective vibration control of thin-walled parts in the whole milling process, a new technology of multiple dynamic vibration absorbers with wide band was presented.The vibration absorbers were arranged closely at the vibration sensitive points of workpiece.The natural frequency of these absorbers was different to realize the optimal control of time-varying cutting vibration. In addition, the parameters of each dynamic absorber were designed by the global optimization method. Considering the minimal amplitude of frequency response function at the vibration sensitive points of workpiece as an optimization objective, the dynamic parameters of the absorbers were obtained by the aid of a finite element analysis software. Finally, the frequency response amplitudes at vibration sensitive points of the workpiece with different wall thickness was analyzed to verify the effectiveness of the vibration reduction method. The results show that after only once mounting,the dynamic vibration absorbers can realize the effective control of the time-varying cutting vibration in the whole milling process. The frequency response amplitude of workpieces generally can be reduced by more than 85%. © 2018, Editorial Office of Journal of Vibration and Shock. All right reserved.
