摘要

为了减小工程中的振动带来的安全隐患与经济损失，磁流变阻尼器作为一种新型减振器件近年来被各行业广泛应用。文章基于往复压缩机管路振动实验平台，应用无线多点振动测量系统，对研制的半主动式磁流变阻尼器在管路中的减振效果进行分析，通过改变磁流变阻尼器电流大小分析该磁流变阻尼器减振情况与电流大小之间的关系。实验结果表明该磁流变阻尼器在管路中起到了较好的减振效果，各测点的振动位移大幅下降，在电流为1.8A时减振效果最好，振动位移降幅达80.70%，分析表明随着电流的增加振动位移大多呈现逐渐减小的趋势。研制的半主动式磁流变阻尼器与传统阻尼器相比具有阻尼可变可调的优点，可较好适应往复压缩机组的长周期变工况安全运行。

Abstract

In order to reduce the potential safety hazards and economic losses caused by vibration in engineering, MR damper, as a new damping device, has been widely used in various industries in recent years. Based on the pipeline vibration experimental platform of reciprocating compressor, the vibration reduction effect of the developed semi-active MR damper in the pipeline is analyzed by using the wireless multi-point vibration measurement system. By changing the current of the MR damper, the relationship between the vibration reduction of the MR damper and the current is analyzed. The vibration damping effect of the magnetorheological damper decreases by 1.80% when the vibration amplitude increases to 8a, which shows that the vibration damping effect of most of the vibration damping points decreases significantly. Compared with the traditional damper, the semi-active MR damper has the advantages of variable and adjustable damping, and can better adapt to the long-term and safe operation of reciprocating compressor unit under variable working conditions.
