Vibration analysis of spinning frame by using modal testing technique

A spinning frame appeared intense vibration problem within working speed region. Using modal testing technique, the vibration of the spinning frame is analysised. Using TD800 machinary condition monitoring system, and Applied Gown Influence Elimination method to identify the modal parameters, the natural frequencies and vibration modes of the support plate, beams, and spinning frame are gotten. By combining the results of modal analysis with the vibration experiments of the whole spinning machine, the cause of exited intense vibration of the frame is found out. Some suggestions for the improvement of the dynamic properties are proposed. This research is helpfull to the design of the spinning frame.
