Abstract
he performance of piezoelectric driven feeder system is discussed and analyzed in this thesis, especially the vibration and the feed rate. First, we established the math model of the feeder system and find out the relationship between dimension parameter and its first resonance frequency by numerical analysis. Then, the dimension of system is determined and can be computed or anticipated its mechanical characteristic.
The ANSYS software offers a method to check the correctness of our math model and hypothesis. At last, make a real piezoelectric driven feeder system as we want and measure its mechanical characteristic (e.g. first resonance frequency and vibratory amplitude of track) to compare with result of numerical analysis.
The ideal feed model must be set up before figure out the feed rate of the feeder system. Three factors that have the most influence on the feed rate can be found out. They are first resonance frequency, slanting angle and amplitude of track. Finally, we can conclude that the feed rate of the feeder system calculated from the formula we proposed in this thesis can be applied to all materials and dimensions.
