Research of Dynamics Simulation of a Six-DOF Segment Erector for Tunnel Boring Machine

Abstract:

In order to solve the problems such as more restriction conditions, complicated interference and longer design periods in the design process of segment erector for Tunnel Boring Machine, it is necessary to study on the dynamics simulation of TBM segment erector. The 3D virtual assembling model of a tunnel segment erector is built based on Pro/E software according to its design parameters such as structure and size. The model is simplified and optimized reasonably and various constraints are applied under variety working conditions. The dynamics characteristics of drives and the forces of each part are obtained and they will provide a boundary condition for strength check and basis for the power system design which is important for the further optimal design. The simulation results also provide an important reference for the mechanism design and type selection design for the power system of segment erector and design cycle is shortened for TBM segment erector.
