Aiming at the problems of high-frequency vibration and strong noise in the operation of coal crusher in the coal handling system, an electromechanical joint suppression scheme combining mechanical structure optimization and electrical control technology is proposed. Starting from the source of vibration and noise of coal crusher, this paper systematically analyzes the mechanism of resonance and acoustic radiation in the process of equipment operation, establishes the multi physical coupling model of transmission system, and introduces the coordinated control strategy of intelligent motor speed regulation and damping vibration absorption structure. Through experimental verification, the combined suppression technology can significantly reduce the overall vibration amplitude and sound pressure level of the system, improve the reliability and environmental friendliness of coal handling equipment, and provide new ideas and empirical basis for the transformation of similar high noise and high vibration industrial equipment.
