【摘要】 玻璃纤维增强复合材料(Glass Fiber Reinforced Plastics, GFRP)具有质量轻、比强度高和耐腐蚀等优异性能，广泛应用于航空航天制造领域。为了研究GFRP/铝合金叠层结构制孔时的轴向力和分层特征，开展GFRP/铝合金叠层结构钻削试验，分析主轴转速和进给速度对GFRP/铝合金叠层结构钻削力和分层特征的影响。研究结果表明，钻削力随着主轴转速的增大而减小，随着进给速度的增大而增大，建立了钻削力经验模型，实测值与理论值误差控制在3%以内，对预测钻削力提供了理论依据。主轴转速越低，进给速度越高，分层特征越明显，高转速低进给有利于减少分层并改善加工质量。更多还原

【Abstract】 Glass fiber reinforced plastics(GFRP) is widely used in aerospace manufacturing with the excellent properties such as light weight, high specific strength and corrosion resistance.In order to study the axial force and delamination characteristics of GFRP/aluminum alloy laminated, the drilling experiments are carried out.The influence of spindle speed and feed speed on the drilling force and delamination characteristics of GFRP/aluminum alloy laminated structure is studied.The experimental results show that the drilling force decreases with the increase of spindle speed, and the drilling force increases with the increase of feed speed.An empirical model of the drilling force is established, the error between the measured and theoretical values is controlled within 3%,which provides a theoretical basis for predicting the drilling force.The lower the spindle speed and the higher the feed speed, the more obvious the stratification characteristics.High speed and low feed are conducive to reducing delamination and improving processing quality.更多还原
