刀盘是盾构机的主要部件,其结构合理与否影响盾构机性能。为了设计合理的刀盘结构,提高设计效率,笔者将参数化设计与优化设计相结合,建立盾构刀盘多目标优化设计流程,从而减少了盾构机刀盘建模的工作量,并利用分析结果进行优化设计,快速获取最优的设计方案。优化结果使得刀盘应力分布更加均匀、刀盘结构刚度增强且质量减少,为盾构机刀盘设计定型提供了参考依据。
Cutter is the main component of the shield machine, its structure is reasonable or not affect the shield machine performance. In order to design a reasonable cutterhead structure and improve the design efficiency, the author combines the parametric design and the optimized design to establish a multi-objective optimization design flow of the shield cutterhead, so as to reduce the workload of the cutterhead cutter modeling and use Analysis results to optimize the design, fast access to the optimal design. The optimized result makes the stress distribution of cutterhead more uniform, the stiffness of cutterhead structure is enhanced and the quality is reduced, which provides the reference for the design of shield cutterhead.
