Cutter Layout on Special-Shaped Cutterhead for Shaft Boring Machine
摘要
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.关键词
