摘要

摘要:
为解决竖井全断面掘进机类“W”型刀盘滚刀布局困难的问题，基于离散元法研究滚刀安装排布参数对滚刀破岩效果的影响规律，通过粒子群优化算法得到滚刀整体布局优化方案. 首先，分别建立掌子面凹陷区域处和锥面处滚刀组协同破岩的二维离散元模型；然后，研究不同布刀间距的凹陷区域处滚刀组协同破岩效果，揭示锥面处滚刀刀间距及安装倾角对岩石破碎情况、滚刀载荷和破岩效率的影响规律，以破岩比能为指标得到合理的锥面处滚刀刀间距和安装倾角；最后，分析确定星型布局方式是适合异型刀盘上滚刀的布局方式，并利用粒子群算法优化滚刀布局方案. 研究结果表明：千枚岩地层中凹陷区域处应该缩小滚刀组的布刀间距；锥面处异型刀盘的滚刀采用垂直锥面安装方式时，岩石破碎效率更高；滚刀布局优化后的异型刀盘径向载荷减小24.07%，刀盘合力矩减少40.83%. 研究成果可为竖井工程中异型刀盘的滚刀布局提供参考.

Abstract:
In order to solve the problem of difficult cutter layout on a W-shaped cutterhead for a shaft boring machine, the influence of cutter installation and arrangement parameters on the rock breaking effect of cutters was studied based on the discrete element method, and the overall layout optimization scheme of cutters was obtained by particle swarm optimization algorithm. Firstly, the two-dimensional discrete element model of the cooperative rock breaking of cutters at the depression area and the conical surface of the tunnel face was established, respectively. Then, the cooperative rock breaking effect of cutters with different cutter spacing at the depression area was studied, and the influence of different cutter spacing and tilt angles at the conical surface on the rock breaking condition, cutter load, and rock breaking efficiency was revealed. The reasonable cutter spacing and tilt angle at the conical surface were obtained by taking the specific energy of rock breaking as the index. Finally, it was found that the star-shaped layout was suitable for cutters on the special-shaped cutterhead, and the particle swarm optimization algorithm was used to optimize the cutter layout scheme. The results show that cutter spacing of cutters should be reduced at the depression area of the phyllite strata. When cutters on the special-shaped cutterhead at the conical surface adopt the vertical conical installation method, the rock breaking efficiency is higher. After the optimization of the cutter layout, the radial load of the special-shaped cutterhead is reduced by 24.07%, and the resultant moment of the cutterhead is reduced by 40.83%. The research results can provide a reference for cutter layout on the special-shaped cutterhead in shaft engineering.
