| Abstract: | The dynamic property of piezoelectric micro displacement actuators (PMDA) for spindle rotation induced error compensation of boring was addressed, including mainly the mechanical characteristic, phase lag property and hysteresis phenomenon. The influence factors of static and dynamic mechanical characteristic and the phase lag property were analyzed systematically. Three main influence factors of the phase lag property were discovered. With comparison to the mechanical Coulomb friction, a generalized model of nonlinear hysteresis of PMDA was advanced, based on the essential analysis of nonlinear phenomenon. Finally, the application of PMDA in an error compensation control system of turning was introduced. A good compensation result was achieved. |
