Simulation Study on Contacting State between Drilled Hole Wall and Guide Pads for Staggered Teeth BTA Drill

  • 摘要: 分析BTA深孔钻削工作原理与受力特点,采用ANSYS软件建立了错齿BTA钻头导向条与孔壁之间的有限元接触分析模型,通过静力学仿真分析,获得了钻削过程错齿BTA深孔钻头导向条与孔壁实际接触状态,研究了接触应力和接触区域随导向条位置角的变化规律。结果表明仿真所获得的接触区域与实际钻削过程导向条的磨损图基本一致,导向条与孔壁的接触主要集中在导向条前端很小的区域,导向条位置角对接触应力与接触区域具有重要影响,通过对导向条位置角的优化可以很好地改善接触状态,为错齿BTA深孔钻头的优化设计提供了依据。
