TBM盘形滚刀破岩过程的数值研究
Numerical Research on Rock Fragmentation Process of TBM Disc Cutter
摘要
Abstract
In this paper, the dynamic simulation and analysis of TBM ( Tunnel Boring Machine) hob cutting rock process is simulated by using ANSYS/LS-DYNA. The load of TBM hob in the cutting process and the effect of cutting parameters such as disc rotation speed and cutting depth of hob effects on the hob cutting load are studied. The results show, when the epitaxial compressive strength of rock is 45 MPa, the average value of the lateral force, rolling force and normal force under the hob is about 0 kN, 0. 45 kN, 4. 5 kN, and the best penetration and rational cutting speed is 10 mm and 3. 6 r/min, which provides a reasonable basis for the de-signing staff parameters under the condition of the second hard rock.关键词
