机器振动级值趋势预示方法的改进

THE IMPROVEMENTS ON APPROACH OF THE VIBRATION LEVEL TREND FORECASTING FOR MACHINERY

机器振动级值趋势预示能为以状态维护取代以时间为基础的预防性维护提供手段。采用灰色预测进行趋势预示,是一种较好的预测计算方法,但存在对随机性因素反应不足的问题,文章探讨了计算方法的改进。最后介绍了趋势预示技术在工业现场的实现方式。

The vibration level trend forecasting for machinery can provid a means of replacing the preventive maintenance following a set time with the maintenance based condition.The adopting Grey Model(GM)in the trend forecasting is a better approach of calculation in the prediction.But the approach of calculation mentioned above has a defect in reaction to the random variation.The ways of the improvements of the this calculating are investigating.At last,the achieving approach of trend forecast technology coming true in the industry on-the- spot is presented.
