摘要

针对碎煤机在输煤系统中运行过程中的高频振动与强噪声问题，提出一种融合机械结构优化与电气控制技术的机电联合抑制方案。本文从碎煤机振动和噪声的根源出发，系统分析设备运行过程中产生共振和声波辐射的机制，建立传动系统多物理耦合模型，并引入智能电机调速与阻尼吸振结构协同控制策略。通过实验验证，该联合抑制技术能显著降低系统整体振动幅度与声压级，提升输煤设备运行的可靠性与环境友好性，为类似高噪声高振动工业设备的改造提供了新思路和实证依据。

Abstract

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.
