英文摘要	An isosceles trapezoid-type stick-slip piezoelectric linear actuator is proposed. Four rectangular piezoelectric ceramic plates bonded on both sides of the flexible skew beam of the isosceles trapezoid flexible mechanism are utilized to generate a bending mode and make the driving foot drive slide to achieve high-resolution and large-stroke linear motion. With finite element method, the angle adjustment of the flexible beam is determined for producing lateral motion of the driving foot of the isosceles trapezoid flexible mechanism. According to the finite element analysis, the isosceles trapezoid flexible mechanism can increase static friction force in slider forward movement stage and reduce kinetic friction force in backward movement stage by lateral motion of the driving foot. An experimental system is constructed, on which a series of experiments are carried out. The results indicate that the maximum output velocity is 601.803 m/s, the maximum output force is 2.8 N, and the minimum stepping displacement is 0.026 m for locking force of 4 N. The stick-slip actuator driven by the piezoelectric ceramic plates is easy to miniaturize to widen its application ranges. 2019, Editorial Office of Journal of Xi'an Jiaotong University.
