- Abstract
Aiming at the problem of shield machine excavation efficiency, the vibration cutting mechanism, cutter trajectory and rock breaking mechanism, shield cutter head modeling, cutting mechanics model were researched. The vibration cutting technology was applied to the excavation process of shield cutter head. Every performance parameters during the working process were analyzed and compared. The way of adding sinusoidal excitation to change the rotation speed of cutter head to realize vibration cutting was put forward. The numerical simulation software LS-DYNA was used. Both single cutter cutting and shield cutter head cutting process were tested. The results indicate that scraper is superior to hob in vibration cutting drag reduction effect. Under the condition of vibration cutting, the stress of cutter head is reducing and the internal energy is increasing.
