【Abstract】 The static and dynamic responses of piezoelectric ceramic actuators are introduced,and the measuring method and systems are also described.The responses of actuators made from antipiezoelectric ceramic material are experimentally studied.The linearity and repeatability of antipiezoelectric kind are very good.In low frequency range below 50Hz,the amplitude frequency curve is straight,the phase frequency curve is linear.The experiment results show that this kind of actuators can be used in precision linear controls.更多还原
