The Application of Vector Spectrum and Its New Technology in the Rotary Machinery Fault Diagnosis

The clew of vector spectrum is introduced,the theory relationship between the vector spectrum and the signals are deduced,and they are applied to the actual fault diagnosis systems.Moreover,it researches in many aspects of the vector spectrum theory;I pose a new dimension collection of illustrative plates expressing method.It shows that as an analysis method of comprehensively processing whirl signals of rotors,the vector spectrum can clearly deal with the relationship between the orbits and positive/negative eddy.We can also identify the turning intention of the rotors,and it is a very practical analysis tool for fault diagnosis of rotary machinery.
