摘要

本文提出了一项研究的振动行为的柔性工件受到铣削端操作。事实上，这种振动行为是至关重要的，特别是当激励频率接近共振时。因此，考虑被动振动抑制，以减弱铣削工件的动态响应，并减少对加工表面粗糙度和平整度的动态影响。为了验证被动振动抑制的有效性，采用有限元模型研究了无被动吸振器和有被动吸振器时加工表面的振动特性和质量(粗糙度和平整度)。

Passive vibration absorber effect on the machining surface quality of a flexible workpiece

This paper presents a study of the vibratory behaviour of a flexible workpiece subject to a milling end operation. Indeed, this vibratory behaviour is critical, especially when the excitation frequency is near to the resonance. For this reason, passive vibration suppression is considered in order to attenuate the dynamic response of the milled workpiece and decrease the dynamic effect on the resulting machined surface roughness and flatness. In order to confirm the efficiency of the passive vibration suppression, the vibratory behaviour and the quality (roughness and flatness) of a machined surface are studied without and with passive absorber (TMD) using a finite-element model.
