针对碳纤维复合材料(CFRP)钻孔易发生缺陷、孔的质量难保证和效率低等问题,基于Hashin准则和PUCK准则构建碳纤维复合材料本构模型子程序,建立CFRP纵扭超声振动辅助钻孔三维实体有限元模型.与普通钻孔过程的轴向力变化情况进行对比,分析主轴转速、进给速度、频率、振幅、纤维铺层角度和钻头顶角对轴向力的影响.结果表明:轴向力随进给速度、频率和钻头顶角的增大而增大,随主轴转速增大而减小,随振幅增大先减小后增大,随纤维铺层角度增大先增大后减小.
Simulation Study on Longitudinal-torsional Ultrasonic Vibration Assisted Drilling of Carbon Fiber Reinforced Plastics
As to the carbon fiber reinforced plastics(CFRP),the drilling is prone to defects,the quality of the hole is difficult to guarantee and the efficiency is low.Based on Hashin criterion and PUCK criterion,the subprogram of constitutive model of carbon fiber reinforced plastics is constructed,and the three-dimensional solid finite element model of CFRP longi-tudinal torsional ultrasonic vibration assisted drilling is established.Compared with the change of thrust force in ordinary drilling process,and the influence of spindle speed,feed speed,frequency,amplitude,fiber layer angle and drill tip angle on the thrust force are analyzed.The results show that the thrust force increases with the increase of feed speed,frequency and drill tip angle,decreases with the increase of spindle speed,first decreases and then increases with the increase of ampli-tude,and first increases and then decreases with the increase of fiber lay angle.
