摘要
本文应用弹性柱体的扭转理论和有限元方法,计算了标准麻花钻横截面的扭转刚度.求出了钻头螺旋角和钴芯厚度对扭转刚度的影响,为今后设计横截面具有最高扭转刚度的麻花钻提供了依据.
In this paper, the torsional rigidity to twist-drill is calculated according to the theory of elastic column and the finite element method. The effect of the web and helix angle on torsional rigidity was shown by figure. It lays a foundation for designing twist-drill with a high torsional rigidity.
