Driving shaft torque coordinated distribution control method of shield tunneling machine cutter head driving system

Abstract

The invention discloses a driving shaft torque coordinated distribution control method of a shield tunneling machine cutter head driving system. A two-layer structure composed of a cutter head rotating speed control layer and a driving shaft torque coordination layer is used in the cutter head driving system, the basic torque of each driving motor is output in the cutter head rotating speed control layer, and stable control over the rotating speed of a cutter head is achieved; the torque coordination amount of each driving motor is output in the driving shaft torque coordination layer, and the balanced distribution of the meshing torque of a small gear is achieved. According to the problems about the stable rotating speed of the cutter head and driving shaft torque balanced distribution, controllers are designed respectively, the adaptability of the cutter head driving system to the suddenly changed load is improved, and the problem of driving shaft torque unbalanced distribution caused by the mechanical property difference of the cutter head driving system and meshing tooth space difference is solved.

Description

technical field

[0001] The present invention designs underground tunnel excavation and construction technical fields such as subway tunnels, submarine tunnels, mine tunnels, coal mine roadways, and oil pipelines, and in particular relates to the coordinated distribution of drive shaft torque of the cutter head drive system of a shield tunnel boring machine that adopts a multi-motor drive mode Control Method.
