This paper presents a lever-type stick-slip piezoelectric actuator based on the lever amplification principle. The proposed actuator can achieve large strokes, high velocity, and bidirectional actuation with a single piezoelectric stack. The finite element simulation of the lever-type flexible hinge is performed, and the designed prototype is tested. When the voltage is 100 V, the maximum forward velocity is 7.69 mm/s under the symmetry of 20%. The maximum reverse velocity is 7.12 mm/s under the symmetry of 80%. The maximum forward and reverse displacement deviation within 10 cycles is 0.88 m, and the maximum load can reach 105 g.
本文提出了一种基于杠杆放大原理的杠杆式粘滑压电致动器。所提出的致动器利用单个压电叠堆即可实现大行程、高速度和双向驱动。对杠杆式柔性铰链进行了有限元模拟，并对设计的原型进行了测试。当电压为100V时，在20%的对称度下，最大正向速度为7.69mm/s。在80%的对称度下，最大反向速度为7.12mm/s。10个循环内的最大正向和反向位移偏差为0.88m，最大负载可达105g。
