摘要
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。
The cutterhead is the main component of the shield machine, and its structure affects the performance of the shield machine. To design reasonable-structured cutterhead and enhance the design efficiency, the parametrization design was combined with the optimization design to establish the multi- objective optimization design process of the cutterhead of the shield machine, so as to decrease the modeling workload of the cutterhead. In addition, the analysis results were used to carry out the optimization design and rapidly obtain the optimal design scheme. The optimization results made the stress distribution of the cutterhead more uniform, the structural stiffness of the cutterhead enhanced and the cutterhead mass lighter, which offered references for the design of the cutterhead of the shield machine.
