Research on Hard Rock Tunnel Boring Machine Based on Digital Mockup

A digital mockup of hard rock tunnel boring machine was built in order to study the design method of these large equipments. Technology of digital mockup is introduced and the application background and practical requirement of tunnel boring machine has been discussed in this paper. The kinematics model and FEM model were built based on this digital mockup. The results of simulation experiment can be used to provide pre-feasibility validation and optimization of the equipment.
