| 摘 要： | 主要研究行波型非接触压电马达的驱动机理，该文引入边界层概念，对振动体产生的边界层进行分析，探讨行波型超声波非接触驱动机理。给出在振于产生的边界层内超声波非接触驱动主要为声流驱动，而在边界层外是由壁面行波产生的斜向声辐射压力驱动。

| Abstract: | In this paper,the driving mechanism of non-contact ultrasonic driving based on traveling wave is analyzed systematically.Based on the theory of the boundary layer,the author obtains the following results: inside of the boundary layer of vibrator,the driving force of the non-contact ultrasonic driving is provided by the acoustic streaming;while outside of the boundary layer,the slider is driven by the acoustic radiation pressure which provides the oblique pressure force. |
