Abstract

Taking the DZ101 TBM(Tunnel Boring Machine) main beam as research object, with CAD/CAE used, a three-dimensional mechanical analysis model of the main beam was established. And then the static mechanical performance of the main beam was studied. The results show that: the maximum stress of main beam is 132MPa and the maximum deformation is 12.48mm, its safety factor is 2.6, which meets the requirements of strength and the stiffness. The results from modal analysis shows that the frequency of main drive-0.13Hz is far less than the lowest frequency of main beam-8.86Hz. Thus, resonance will not occur. By comparing the results from the field tests, simulation results is verified.
