An electromechanical coupling model of TBM's main driving system

The damage in driving system's core part of TBM caused by pinions' asymmetrical load is very serious. The traditional design lacks the coupling relationship between the mechanical and control system, which leads to the bottleneck of the TBM's driving system's symmetry. This paper considers the dynamic character and control system of the TBM's driving system. An electromechanical coupling model is proposed based on torque's in-time interactive. Take the engineering project as example, the calculation was proceeded based on the original model. The result shows that after a gear frequency cycle, the torque of the motor with maximum load increased by 4.46%, and the minimum one decreased by 9.00%.
