Abstract: Compared with the rigid-flexible coupling dynamic models that had been constructed in other published papers, comprehension about the equation of rotating flexible beam based on the method of small element is presented, and some fuzzy understanding are clarified.Numerical simulations on the vibration control of rotating flexible beam with positive position feedback are carried out. More over, using piezoelectric ceramic as sensors and actuators, several experiments are performed, their results are shown and discussed.
