针对滑动轴承运行状态直接影响旋转机械运行的安全与可靠性问题,充分利用实测轴振和瓦振数据,对轴心轨迹、轴颈中心位置变化、轴振和瓦振之间的比例关系进行了分析和研究,提取了轴承运行状态信息特征,对轴承运行状态进行综合评判,介绍并分析了几个旋转轴系故障的工程实例,证明综合应用轴振和瓦振信息融合的分析方法可较好地判断滑动轴系的工作状态.
Aiming at the problem of safety and reliability of the sliding bearing operation, which directly affects the operation of the rotating machine, taking full advantage of the measured shaft vibration and the vibration data, the proportional relationship between the axial locus, journal center position, shaft vibration and tile vibration Analysis and research, the information of bearing operating status is extracted, and the running status of the bearing is comprehensively evaluated. Several engineering examples of the failure of rotating shaft system are introduced and analyzed. It is proved that the comprehensive analysis method of shaft vibration and tile vibration information fusion can be better To determine the working status of the sliding shaft system.
