Analyses of dynamic characteristics and structure optimization of tunnel boring machine cutter system with multi-joint surface

There will be structural failure in the cutter system with different degrees due to the vibration of cutters. Moreover, in the extreme environment, the dynamics behavior of the cutter system is hard to predict, and it is difficult to realize the anti-vibration design of cutters. Therefore, it is of great theoretical value and engineering significance to analyze the dynamics characteristics of tunnel boring machine (TBM) cutter system, optimize...
