摘要

卷包设备噪声对操作者的劳动健康造成了一定影响,业内对于降噪措施的研究有若干成果,多以声波吸收材料运用和声源隔绝措施为主要降噪手段,但效果和效费比有待进一步提高,而本文所提出的被动式动力吸振系统可与传统降噪技术综合使用,达到噪声职业危害综合治理的目的。本文主要研究对象是烟草加工企业的卷烟包装设备,有针对性地提出了一种被动式动力吸振系统,通过采集机组的噪声及振动信号,经系统软件分析后向动力吸振器发出调节刚度的指令以改变吸振参数,抑制关键位置的振动来降低噪声辐射;本文通过前期现场调研,收集噪声基频数据确定噪声类型和来源,建立被动式动力吸振系统数学模型,从动力吸振系统原理、变刚度技术及控制算法等方面阐述了该系统的组成结构和相关原理,为噪声治理提供了一种新思路。

Abstract

The noise of packaging equipment has a certain impact on the labor health of operators, and there are some achievements in the research of noise reduction measures in the industry. Most of them use acoustic absorption materials and sound source isolation measures as the main noise reduction means, but the effect and cost-effectiveness ratio need to be further improved. The passive dynamic vibration absorption system proposed in this paper can be integrated with traditional noise reduction technology. To achieve the purpose of comprehensive control of noise occupational hazards. The main research object of this paper is the cigarette packaging equipment of tobacco processing enterprises, and a passive dynamic vibration absorption system is proposed. After collecting noise and vibration signals of the unit, the system software analyzes and sends stiffness adjustment instructions to the dynamic vibration absorber to change vibration absorption parameters and suppress vibration at key positions to reduce noise radiation. Based on the preliminary field investigation, this paper collects the noise base frequency data to determine the noise type and source, establishes the mathematical model of the passive dynamic vibration absorption system, expounds the composition structure and related principles of the dynamic vibration absorption system from the aspects of the principle of the dynamic vibration absorption system, variable stiffness technology and control algorithm, and provides a new idea for noise control.

Key words: Dynamic vibration absorption; Variable stiffness technology; Control algorithm
