摘　　要：针对某土压平衡盾构(EPB)刀盘,以刀盘质量、强度和刚度为优化目标,基于Workbench平台建立了刀盘参数化设计优化模型,采用多目标遗传算法进行求解,得到了3种优化方案。针对刀盘应力集中处局部结构进行改进,有限元分析结果表明适当增加牛腿壁厚和选择合适的牛腿轴线与面板之间夹角值,能有效提高刀盘的力学性能。In view of the earth pressure balance shield （EPB） cutter structure, this paper takes its quality, strength and stiffness as object of optimization, establishes the cutter parametric design optimization model, based on Workbench platform, and uses a multi -objective optimization method to solve the problem and obtain three kinds of optimization schemes. The finite element analysis result of new plan shows increasing the wall thickness of corbels appropriately and choosing the angle between cutter and corbel reasona-bly can improve the cutter structure performance.
