Abstract

It is very important to measure and analyze vibration and diagnose fault for the operating safety of large-scale machine. Using the NI9233, a four-channel simultaneous data-acquisition module, and the LabVIEW, a convenient virtual instrument of vibration measurement and dynamic balancing is developed. In order to measure accurately the vector of fundamental frequency of vibration rotor, the method of soft track sampling is presented. With the LabVIEW, a field dynamic balancing program based on the influence coefficient method is developed, which can carry out single-plane or two-plane dynamic balancing. The experiment shows that the instrument is precise in measurement and balancing, reliable in work, and convenient in operation.
