Study of Loading Theory of Hard Rock Roller Based on CSM Model

相比圆形刀盘,在滚筒式刀盘上安装盘形滚刀更容易实现矩形断面的开挖,该技术有望广泛应用于硬岩矩形隧道施工。以滚筒式刀盘在破岩过程中的力学参数研究为目标,通过建立了滚筒刀盘的数学模型,确立了盘形滚刀切削轨迹的参数方程,得出滚筒刀盘的切削物理参数,结合CSM模型,推导出硬岩滚筒载荷的力学方程。该理论研究,为滚筒式刀盘优化设计和力学预测提供了理论依据。

To round disc cutter,rectangular cross section could be easily excavated by installment disc cutter on roller cutter,the technology was hopeful to widely used in hard rock rectangular tunnel construction.And mechanics parameters during rock broken process with roller cutter were studying aim,and then mathematical model of roller cutter was built,so parameter formula of cutting trace of roller cutter was built,so some physical parameters were obtained,with CSM model,mechanics formula of hard rock roller loading was deduced,according the theoretical studying,it provided theoretical foundation for optimal design for roller cutter and mechanics forecast.
