Abstract
In the process of vibration monitoring, position error of sensors and transformation between acceleration and displacement of vibration signal may influence the accuracy of vibration monitoring. This paper presents an algorithm based on spatial vector transform and frequency domain integral. And a vibration monitoring system is also developed. Experimental results show that the vibration coupling caused by position error of sensors can be eliminated by signal transformation, which is useful to identify vibration source. Furthermore, the errors of accuracy and phase exist in conventional integral algorithm can be overcome by using frequency domain integral in the conversion between acceleration and displacement. So, higher accuracy conversion can be acquired in this way. The monitoring system can offer accurate data to distinguish the vibration state of machine tool with stable property.
