刀盘是全断面隧道掘进机(Tunnel boring machine，TBM)的关键部件，TBM刀盘系统设计直接关系掘进效率和可靠性。刀盘系统设计的关键是复杂岩石边界下刀群布置设计与刀盘盘体结构设计，二者相互耦合，相互影响。分析刀群与盘体支撑结构之间空间位置耦合以及支撑结构与刀盘强度刚度之间的非线性耦合关系，建立刀群与盘体支撑结构耦合布置优化模型，提出多子系统协同进化的刀具适应性布置与盘体结构耦合设计方法。以引洮工程为例进行验证，结果表明：支撑筋初始安装角与刀盘强度、刚度之间存在非线性函数关系，多子系统协同进化方法求解出的刀群与支撑筋耦合布置方案的最大等效应力、最大变形量、不平衡力矩、不平衡力、顺次角度等指标相比原方案降低了30%以上，以此证明提出的耦合优化模型及其求解方法的可行性和有效性，可为TBM刀盘系统设计提供一定的借鉴与方法支撑。

Cutterhead is one of the key parts of full face tunneling boring machine(TBM) and the adaptive design of cutterhead topology structure of the TBM directly affects its boring efficiency and reliability. The key issue of the cutterhead topology design lies in the adaptive layout design of disc cutters group and the cutterhead structure design under the complex rock boundary conditions;they are mutual coupling and mutual influencing. It has been analyzed that the coupling relation between the disc cutters group and the cutterhead structure, and then the nonlinear coupling model between the cutterhead structure and the cutterhead strength and stiffness has been established. Finally the multi-objectives coupling layout design model between the disc cutters group and the cutterhead structure has been constructed and the corresponding multi-subsystem co-evolutionary solving method has been proposed. Taking the practical“Yintao”project as a background, the numerical simulation results have shown that:compared with the original design of cutterhead, the values of maximum stress, maximum deformation, unbalanced moment, unbalanced force, sequential angle and other indicators of the optimal layout design solved by the proposed method have reduced by 30% or more, which has proved the feasibility and efficiency of this method and its capability of providing technical support for engineers.
