为保证盾构刀盘在使用过程中的强度和刚度,采用ANSYS软件对盾构刀盘进行有限元结构应力应变分析,得出结构设计缺陷。通过对刀盘优化化设计,合理配置刀盘各个设计性能参数,不但提高了刀盘整体安全性能,而且能够提高材料利用率,达到减重降低成本的效果。 In order to ensure the strength and rigidity of the shield cutter in use, ANSYS software was used to analyze the stress and strain of the shield cutter by finite element method, and the structural design flaws were obtained. By optimizing the design of the cutterhead and rationally configuring the design parameters of the cutterhead, not only the overall safety performance of the cutterhead can be improved, but also the material utilization ratio can be improved, and the effect of weight reduction and cost reduction can be achieved.
