Virtual Prototype Simulation of Fine-Adjustment System Kinematics for Segment Erector of Tunnel Boring Machine

In this paper, we present the modeling and kinematics simulation of fine-adjustment system for segment erector of tunnel boring machine (TBM), which is performed in the virtual prototype platform. The 3D virtual assembling model of fine-adjustment system is built with Pro/E software according to its design parameters such as structure and size. After the interference inspection, the model is imported into ADAMS through the interface module of Mech/Pro. The model is simplified and optimized reasonably and various constraints are applied under variety working conditions. The results of simulation show that the design has three degrees of freedom movement capacity which meets the design requirements. At the same time the kinematics characteristics of each part along three different directions are obtained and they will provide some references for the further optimal design.
