- Abstract
The prediction of mechanical parameters of shield cutter head can improve the calculation and calibration accuracy of cutter head and also provide technical support for the adjustment of shield construction parameters. Combined with the shield cloud platform developed by China Railway Engineering Service Co., Ltd., the left line boring data of a section of Shenzhen Metro Line 14 is applied to extract engineering parameters affecting thrust and torque in shield construction based on theoretical analysis, and the relation between relevant parameters and the thrust and torque is calculated by grey relation analysis method. BP neural network is used to establish a prediction model with stratum parameters, cutter head parameters and boring parameters as input and shield thrust and cutter head torque as output, and the training and optimization of the model are completed by using shield cloud data. Based on the mechanical analysis process of cutter head, combined with the load prediction model and the parametric modeling system of cutter head design, an integrated platform with functions of shield cutter head parameter prediction and mechanical analysis is established to realize the automation of simulation analysis of cutter head design.
