摘要

薄壁类工件由于其刚性较差，在铣削过程中相对于厚壁工件来说更易产生振动，因此需要采取一些措施来抑制颤振。从调谐质量阻尼器（TMD）的吸振原理出发，根据有限元分析和模态试验结果设计了抑振辅助夹具。所设计的辅助夹具不需要额外的动力装置、结构简单、易安装、灵活方便且适用性广。试验结果表明，采用抑振夹具后，机匣零件铣削过程中系统的低阶振动幅值降低了90%，高阶振动幅值降低了70%，刀具和工件的耦合振动幅值降低了80%。

Abstract

Milling thin walled structures is challenging due to their low stiffness and hence consequential vibration problems. So some measures need to be taken to suppress chatter. Based on the vibration absorption principle of tuned mass damper (TMD)

the vibration suppression auxiliary fixture is designed according to the finite element analysis and modal experiment results. The proposed auxiliary fixture does not require additional power unit

with simple structure

easy installation

flexible and convenient advantages and can be widely used in industrial manufacturing. The experimental results show that the amplitude of the low frequency vibration of the system reduced by 90%

the amplitude of the high frequency vibration reduced by 70%

and the coupling vibration amplitude of the tool and the workpiece reduced by 80%.
