Finite element analysis for TBM’s host machine with CATIA

Host machine is the most important part of TBM. The design ability of the host machine of TBM decides the performance of the TBM. CATIA is a famous CAD/CAE/CAM software. It is adopted to bulid 3D model and complete the finite elements analysis of host machine of TBM. Some important informations about design of host machine of TBM were getted,at the same time finite elements analysis of complicated stucture was researched. By analyzing these informations,the influence of structure and design parameters to the performance of host machine of TBM was obtained.
