A new type of arc-plate flexible driving foot stick-slip piezoelectric actuator

Abstract Because of its high precision and high speed, stick-slip actuators in piezoelectric actuators have important research significance in aerospace and other fields. To make the performance of the actuator superior, a high-performance stick-slip actuator suitable for the aerospace field is developed. In this paper, based on the in-depth study of the related theories, a kind of arc-plate flexible driving foot is proposed. On this basis, a kind of arc-plate flexible driving foot stick-slip piezoelectric actuator is designed to further improve the performance of the actuator. After the test, its maximum speed can reach 4.12 mm/s, and the maximum load is 330 g.
