ABSTRACT
As key coal mining equipment, the shearer is crucial for improving adaptability to complex conditions, extending service life, and reducing failure rates—key to enhancing coal production economic benefits. Using the transmission system model, dynamic bearing contact forces, vibration acceleration at virtual measurement points, and vibration levels in gangue/pure coal conditions are analyzed. The reliability and accuracy of the finite element analysis for the cutting unit's vibration characteristics were validated via bench test comparison. The vibration-data-equipped housing is input into acoustic boundary element simulation; combined with the built model, noise variations at different sound field response points with gear face width and bottom clearance coefficient are derived. Results show high-order modal analysis confirms no system resonance risk. When the motor gear face width is 74mm, planetary gear train face width 140mm, and bottom clearance coefficient 0.4, the gears exhibit excellent load-bearing capacity, stability, and low vibration/noise.
