ABSTRACT
This study addresses the insufficient dynamic strength and low energy efficiency of continuous miners in complex coal seams. A rigid-flexible coupled virtual prototype of the EML340 miner revealed that stress at the cutting arm's hydraulic cylinder connection exceeds the allowable limit (125 MPa). Based on single-factor analysis of cutting parameters and coal-rock hardness, an intelligent Fuzzy Neural Network (FNN) controller was designed to optimize performance under stress constraints. Co-simulation using ADAMS and MATLAB/Simulink demonstrates that the system adaptively adjusts rotational and swing speeds in response to hardness variations. Compared with PID control, the FNN strategy reduces settling time by 87.5%, stress overshoot by 28.6%, and specific cutting energy by 9.3%, ensuring safety while enhancing efficiency. Simulation accuracy was validated via a physical cutting test bench, with a maximum relative error of 4.92% in vibration characteristics. This research provides a technical solution for achieving intelligent, efficient, and safe cutting in continuous miners.
