摘　　要：为解决深孔加工中高速钻削不平稳、排屑不流畅等问题,设计了一种新型高速深孔钻头。基于ANSYS有限元软件,建立了深孔钻三维模型,对其施加载荷与约束,并进行六面体SWEEP网格划分。对新型高速深孔钻进行应力应变、疲劳强度数值模拟计算,得到应力及变形数据。经改进后的深孔钻应力集中在有切削刃的一侧,工作过程中所受最大应力远小于材料许用应力,强度、刚度均满足要求。In order to solve the problems of unstable high-speed drilling and influent chip removal in deep hole machining,a new high-speed deep hole drilling structure is proposed.Based on ANSYS finite element software,a three-dimensional model of deep hole drilling is established,and when the load and constraint are applied to it,the hexahedron SWEEP mesh is generated.Stress and deformation data are obtained by numerical simulation of stress strain and fatigue strength of a new high-speed deep-hole drill.The results show that the stress of the improved deep hole drill is concentrated on the side with the cutting edge,and the maximum stress in the working process is far less than the allowable stress of the material.Both the strength and stiffness meet the requirements.
