Machinery condition recognition and fault diagnosis of spindle based on LabVIEW

Based on the vibration signal of the spindle in the harsh working conditions, proposes an algorithm for the condition recognition and fault diagnosis of the spindle, and designs a system of condition recognition and fault diagnosis of the spindle based on LabVIEW.The verification of a horizontal machine tool spindle shows that the system can detect the shaft-misalignment of the spindle front end, provide professional guidance for maintenance staff, and have good engineering application value.
