通过对盘形滚刀破岩过程的深入研究,建立了盘形滚刀破岩的三维力学模型,提出了求解此模型的单点双角度变量理论,用此理论研究了在全断面岩石掘进机破岩过程中盘形滚刀与岩石相互作用引起岩石形变的几何方程和物理方程;建立了盘形滚刀与岩石相互作用的平衡方程,据此导出了盘形滚刀破岩的垂直力、滚动力和侧向力的解析表达式,从而提出了盘形滚刀破岩理论研究的新方法。
Through the deep research on the rock breaking process of disc cutter, a three-dimensional mechanical model of rock breaking by disc cutter was established and a single-point double-angle variable theory for solving this model was proposed. Using this theory, The geometric equation and physical equation of the rock deformation caused by the interaction between the disk cutter and the rock during rock breaking are established. The equilibrium equation of the interaction between the disk cutter and the rock is established. Based on this, Rolling force and lateral force of the analytical expression, thus put forward a disc cutter rock breaking theory of new methods.
