Abstract

The circular saw blade is widely applied in rock processing; its cutting performance significantly impacts rock processing. Therefore, the numerical simulation model of rock cutting with the flexible circular saw blade has been established to investigate the effects of cutting parameters on the stress and cutting force of circular saw blade, and the damage and stress of rock in the circular saw blade cutting into rock vertically at constant feed speed and rotation speed. The research results indicate that the stress of the saw blade and rock rises with the increase of feed speed and rotation speed of the saw blade. Furthermore, the rock damage and the cutting force of the circular saw blade increase with the increasing feed speed and decrease with increasing rotation speed. The circular saw blade cutting force, vertical force, and horizontal force increase with the rising distance between the double circular saw blade. However, the axial force decreases. The research results of cutting hard rock with the flexible circular saw blade can aid in the optimization of cutting parameters and improve cutting efficiency.

基于ANSYS/LS-DYNA的圆锯片切削性能研究

圆锯片在岩石加工中应用广泛;其切削性能对岩石加工有重要影响。为此，建立了柔性圆锯片切割岩石的数值模拟模型，研究了在恒定进给速度和转速下，切割参数对圆锯片应力和切割力的影响，以及圆锯片垂直切割成岩石时岩石的损伤和应力。研究结果表明，随着进给速度和锯片转速的增加，锯片和岩石的应力增大。随进给速度的增加，岩石损伤和圆锯片的切削力增大，随转速的增加而减小。圆锯片的切割力、垂直力和水平力随着双圆锯片间距的增大而增大。但轴向力减小。柔性圆锯片切割硬岩的研究成果有助于优化切割参数，提高切割效率。
