摘要： 针对全断面掘进机刀具布置规律问题,分析了全断面掘进机刀盘的破岩机理,建立了全断面掘进机工作时的刀具受力模型并提出了如何提高刀盘破岩性能的方案.构建了带复杂约束的多变量非线性目标数学模型,并采用智能算法开发了一种针对盾构刀盘上刀具布置规律的优化程序.以EPB6.28型全断面掘进机刀盘为例进行了优化设计,建立了刀盘数字化样机并对其进行了力平衡仿真验证.对两种刀盘在刀具磨损和力平衡性能比较分析,结果表明与原刀盘相比新设计的刀盘具有更加良好的实用性.

Abstract: The rock-broken mechanism during the operation of the cutter head of TBM(tunnel boring machine) was analyzed to study the layout of cutters. A model of the cutters under the action of forces during TBM's working was therefore developed, thus proposing a scheme to improve the rock breakability of TBM's cutter head on which the cutters are lay out. Then, a nonlinear multi-objective mathematical model with complex constraints was developed, with an optimization program provided via an intelligent algorithm for the layout design of cutters on the tunnel shield/cutter head of a TBM. Exemplifying the cutter head of an EPB6.28 TBM, an optimized design was given to set up a prototype with digitized cutter head, to which a simulation was done for the verification of equilibrium of forces. Comparing analytically the cutter wear and equilibrium of forces between a previous and a newly designed cutter heads, the results showed digitally that the new one is more practicable than the previous one.
