利用可靠性统计数据,提出了磨煤机的可靠性增长模型,详细讨论了该模型的参数估计和拟合检验。并以电力可靠性管理中心统计数据为例,验证了该模型完全符合被统计的磨煤机可靠性增长趋势。分析结果表明磨煤机的可靠性得到逐步提高。 Based on the reliability statistics, the reliability growth model of coal pulverizer is proposed. The parameter estimation and fitting test of the model are discussed in detail. Taking the data of power reliability management center as an example, it is verified that the model is in full compliance with the increasing trend of coal mill reliability. The results show that the reliability of the coal mill has been gradually improved.
