本文选取液压泵的流量为参数,用灰色预测方法预测了泵的使用寿命,用True BASIC语言编程计算,并把灰色预测方法的预测结果同回归法、时间序列分析法的预测结果进行了比较,证实了灰色预测方法对液压泵的寿命预测是有效的,且预测精度高。
In this paper, the flow rate of the hydraulic pump is taken as the parameter. The gray prediction method is used to predict the service life of the pump. The program is programmed in True BASIC language. The prediction results of the gray prediction method are compared with those of the regression method and the time series analysis method. It is confirmed that the gray prediction method is effective for the life prediction of the hydraulic pump and the prediction accuracy is high.
