Abstract
The multi-power coupling transmission system (MPCTS) is an electromechanical coupling system, which typically use two or more induction motors to provide its driving torque. It is used in various industrial applications, such as cutter header driving systems of tunnel boring machinery, and yaw systems of wind turbines. In practical engineering applications, the loads borne by the MPCTS are very complex, including both torque loads and non-torque loads. Its dynamic characteristics are affected by both the gear transmission system and the drive motors. For this study, an electromechanical coupling dynamic model of the MPCTS, coupled with a gear transmission system, induction motor, and non-torque load, was constructed to analyze its dynamic characteristics under a non-torque load condition. The results showed increased offsets from the gear vibration equilibrium position, as well as deterioration in system load-sharing characteristics from increases in non-torque load and rotational speed. However, the influence of the non-torque load was significantly greater than that of the rotational speed.
