【摘要】 针对复合材料薄壁件在阵列式柔性工装装夹下进行铣边加工的变形问题，通过有限元软件ABAQUS对其铣削过程进行模拟仿真。研究了POGO柱间距、POGO柱到边沿的边距，以及复材薄壁件主要纤维角度对铣边变形的影响规律。提出了柔性装夹时的薄壁件变形预测方法，可以有效预测间距、边距、角度等参数影响下的薄壁件的变形，对薄壁件边沿自重变形预测的误差值最大为3.6%，对薄壁件边沿外力变形预测的误差值最大为2.70%。更多还原

【Abstract】 Aiming at the edge-milling distortion problem of the composite thin-walled workpiece,which is clamped on the flexible tooling system,the milling process is simulated by finite element method with commercial software ABAQUS.The influence of POGO column spacing,POGO column to edge margin,and the main fiber angle of composite thin-walled parts on the milling deformation is studied.A method for predicting the deformation of thin-walled parts during flexible clamping is proposed.This method can effectively predict the deformation of thin-walled parts under the influence of parameters such as spacing,margins,and angles.The method has a maximum error value of 3.6% for the prediction of the edge weight deformation of thin-walled parts,and a maximum error value of 2.70% for the prediction of the external force deformation of the edge of the thin-walled parts.更多还原
