| Abstract: | Based on different friction coefficients between touchable feet and touchable face when actuator moved toward right and left, a suit of inertial linear actuator driven by piezoelectric stack with changeable friction coefficients was designed and manufactured with piezoelectric stack and mass as power devices. The work principle and movement situation of the actuator were analyzed.A special test system was built to test the performance of the actuator.The results show that the actuator is able to work with the minimum stable step of 0.19 μm, the maximum moving velocity of 11.82 μm/s, and the maximum loading capacity of 900 g at frequency of 10 Hz. |
