锚杆PDC钻头主要几何参数的优化研究

PDC锚杆钻头因直径小和独特的布齿方式,对其强度有着更高的要求,而切削齿的齿前角和侧转角对其强度影响显著,且工作角对切削齿的切削效率和工作性能有着重要的影响。因而确定合理的齿前角和侧转角是钻头设计中至关重要的环节。在ANSYS下,建立了钻头的参数化模型,从不同应用方面考虑,对切削齿的齿前角、侧转角做了优化分析,得出了不同使用条件下的最优值,为钻头的合理设计提供了理论依据。

Optimization Research on the Main Geometrical Parameters of PDC Anchor Bit

PDC cutter intensity has a higher demand because of the small diameter and unique way of placing cutting,and the working angles of the cutter have an important influence on the cutting efficiency and performance.And therefore the proper design of the cutter on the cutting angle and the side angle is very important in the design of PDC bits.Based on finite element soft ware ANSYS,the cutting angle and the side angle of the PDC cutter are optimized.Applications from different considerations,the main geometric...
