| description | Tunnel boring machine (TBM) is seriously damaged during tunneling due to excessive vibration. Insufficient research on the TBM vibration mechanism has led to low accuracy in the calculation of the dynamic response of the TBM main drive system under uncertain load. In this paper, multi-degree-of-freedom coupled dynamics model of the main drive system containing the cutterhead, gear drive, shield, and propulsion system was established, taking bearing and drive gear nonlinear contact forces, uncertain load into account. A multi-position vibration test was carried out based on practical engineering. The vibration mechanism and vibration transmission law along the main structure are studied. The results show that the frequency response of the cutterhead presented a wide frequency domain bandwidth. The main frequency band of support shell is concentrated at 18–20 Hz, which is mainly caused by the excitation of the first three-order natural frequencies of the system under the action of the system’s broadband external excitation load. At the same time, it is found that the coupled vibration of radial overturning vibration and lateral translation vibration is easy to appear in the actual system vibration. The influence of the main mass and stiffness parameters of the system on the various modes of the system is analyzed. The overturning vibration of the shield body has a significant “amplification effect,” and its amplitude reaches 123.60% and 118.99% of the cutterhead, respectively. This study provides a basis for the system’s dynamic design and evaluation of the TBM performance in tunnel construction. |
