摘要
机器振动级值趋势预示是在状态监测和故障诊断的基础上,通过空间和时间的综合分析,进一步对机器工作状态的现状和发展进行分析和预测。文章叙述了机器振动级值趋势预示的基本概念,介绍了趋势预示的判据和评定方法,提供了机器振动级值趋势预示的一种计算方法。本项技术已在工业现场的大型机组上获得了实际应用。
The vibration level trend forecasting for machinery is further the analysis and prediction to the present situation and the development of machinery system,based on the condition monitoring and the fault diagnosis,by the comprehensive analysis of space and time.The basic concept of the vibration level trend forecasting is narrated in this paper.The criterions and the ways of judgement are introduced.A way of calculating for vibration level trend forecasting is provided.At last,this technology of vibration level trend forecast coming true in the industry on-the-spot to heavy machinery is presented.
