Research of Kinematics Simulation of TBM Segment Erector Based on Virtual Prototype

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 kinematics simulation of TBM segment erector. First of all, the kinematics characteristics of segment erector are analyzed; the 3-D model is designed in Pro/E environment; the model is imported into ADAMS and the dynamic simulation is finished finally. After the analysis of simulation of this mechanism, the curves of the speed for the driving parts are obtained and the maximum speeds of driving parts are identified with the method of space search technology. The kinematics characteristics of TBM segment erector are obtained. The simulation results provide an important reference for the mechanism design and type selection design for the power system and design cycle is shortened for TBM segment erector.
