Abstract:To analyze the dynamic characteristics and hot state characteristics of high speed motorized spindle, a set of vibration and temperature data acquisition system of high-speed motorized spindle based on LabVIEW was designed.The system is mainly composed of piezoelectric acceleration sensor, integrated temperature sensor, data acquisition card, frequency converter and computer, meanwhile use LabVIEW2009 virtual instrument development platform, and it can realize the high speed motorized spindle vibration and temperature signals in the operation of the real time acquisition and processing, signal waveform display and storage.
