薄壁零件的铣削强迫振动预测
Forced vibration prediction for milling thin-walled workpiece
摘要
Abstract
To predict the time-varying forced vibration characteristics during milling of such workpieces,the generation mechanism of forced vibrations in the thin-walled workpiece milling was analysed,and experimental modal analysis and cutting experiments were conducted on specimens with varying wall thicknesses.Based on modal theory,the contribution rates of the first three modes of the thin-walled workpiece during milling were quantitatively analysed.A prediction model for the time-varying forced vibration amplitude of the workpiece was established according to these modal contribution rates.Experimental validation results show that the proposed prediction method could accurately characterize the time-varying vibration features of the thin-walled workpieces,providing an effective theoretical basis for formulating vibration suppression strategies and optimizing machining process parameters.关键词
