提出了一种基于双足驱动的压电超声直线驱动器。驱动器采用菱形双足机构，产生两条同步的矩形驱动轨迹。在两个同步轨迹的帮助下，该驱动器可以提供稳定的远程运动（设计的最大行程为19 mm），同时具有大的负载能力和高的驱动分辨率。详细介绍了双足的结构和工作原理，分析了双足的驱动轨迹。对驱动机构进行了有限元分析，研究了驱动机构在各步的静态变形和应力状态。建立了实验系统，对样机进行了性能测试，结果表明，样机能够稳定地分步运行，各步重复性好。驱动器原型的驱动分辨率（最小步长）为25.9 nm。最大负载能力和最大推力分别为37.2和3.2 N。实验结果也证实了所设计的驱动器可以通过改变驱动电压和驱动频率来实现不同的运动速度。
This article presents the piezoelectric ultrasonic linear actuator based on binate feet driving. The actuator is equipped with a rhombus binate feet mechanism to generate two synchronous rectangle driving trajectories. With the help of the two synchronous trajectories, the proposed actuator can deliver stable long-range motion (the designed maximum stroke is 19 mm) accompanying with large loading capacity and high driving resolution. The configuration and operational principle are described in detail and the driving trajectory of the binate feet is analyzed. Finite element analysis is conducted to investigate the static deformation and stress status of the driving mechanism at every step. The experimental system is established to test the performance of the actuator prototype and the results indicate that the prototype can be operated stably step by step and all steps have high reproducibility. The driving resolution (minimum step length) of the actuator prototype is 25.9 nm. The maximum loading capacity and the maximum thrust are 37.2 and 3.2 N, respectively. The experimental results also confirm that the designed actuator can achieve various motion velocities by changing the driving voltage and driving frequency.
