| 摘 要： | 灰关联分析方法是一种实用性强、可信度高的设备故障诊断方法,但其存在一定的应用限制。将D-S证据组合规则与灰关联方法相结合,能有效地处理故障征兆与故障类型关系的复杂性与不确定性,且诊断结果可信度较高。通过对某船用制冷系统故障实例计算,证明该方法简单、实用、诊断准确率高。

| Abstract: | Though the grey relational analysis method has strong practicability and high reliability for equipment fault diagnosis,it is limited in applying.If the D-S evidence theory combination rules is combined with the grey relational analysis method,it can availably deal with the complicated and uncertainly relation between fault symptom and fault category,and the diagnosis result has high reliability.It is validated that the provided method is simple,practical and diagnosed exactly,by means of the calculation on... |
