摘要
针对旋转机械并发故障诊断中难以准确诊断出来的实际情况,研究利用证据理论在不确定性的表示、量测和组合方面的优势,并引入了人工免疫系统以弥补证据理论单独诊断时的一些缺陷。将证据理论与人工免疫系统结合起来作为一种解决并发故障的方法,为并发故障的诊断提供了一种新的思路,并且其可行性在试验中得到了的验证。
A model of multi-parameter comprehensive diagnosis system was proposed with respect to the facts that it was difficult to distinguish during the fault diagnosis process of rotating machine.The evidence theory has the advantages of representation of uncertainty,measurement and portfolio.The introduction of artificial immune system to solve the defects of evidence theory,the artificial immune system and fault diagnosis as a method of solving concurrent faults.This method is verified and provides a new way to solving concurrent faults.
