【Abstract】 Continuous friction fault is one of familiar faults in rotating machine.Commonly the backward whirl phenomenon is one of key diagnostic foundations of continuous friction fault.However,in practice,in most case the backward whirl information can be gotten only when there is the key phase signal,which increases the difficulty diagnosing it.Diagnostic method of continuous friction fault is studied by vector spectrum technology with no key phase signal.An example is presented to validate the method.The results show that the backward whirl can be judged easily by second vibration vector,and the position and range of continuous friction can also be gotten by vibration vector angle.The research results present a efficient method for the diagnosis of continuous friction fault.更多还原
