摘要:
依据福州滨海快线实测数据，利用有限元软件对刀盘掘进进行数值模拟，分析了不同掘进速度、不同转矩下刀盘的受力。结果表明:岩石越坚硬，刀盘的掘进速度越低，刀盘的转矩和旋转速度越高;随着极径增大，刀轴的应力平均值逐渐增大，刀盘的应力平均值呈现先增大后减小的趋势，极径大的刀轴处和刀盘中间位置易受到破坏;刀盘始发阶段易受到冲击荷载，其应力值较大，之后应力逐渐递减，最后趋于稳定。
Abstract:
Based on the measured data of Fuzhou Binhai Expressway, the finite element software was used to numerically simulate the cutterhead excavation. The force analysis of the cutterhead was carried out under different excavation speeds and torques. Analysis shows that the harder the rock, the lower the excavation speed of the cutterhead, and the higher the torque and rotation speed of the cutterhead; as the pole diameter increases, the average stress value of the cutter shaft gradually increases, and the average stress of the cutter head increases first and then decreases. The cutter shaft and the middle position of the cutter head with larger pole diameters are prone to damage; during the initial stage of the cutterhead, it is susceptible to impact loads, resulting in high stress values. Subsequently, the stress gradually decreases and eventually stabilizes.
