中文摘要:

分析了目前直线型超声电机夹持装置存在的问题,并针对双变幅杆V形定子结构提出了双层板簧夹持方案。双层板簧结构可限制定子沿驱动方向的自由度,从而提高了电机的机械性能,其双层平行结构可有效地解决定子工作过程中的扭转,提高了电机的稳定性,电机最大输出力达17.7 N,最大功率为0.67 W,最高效率为19.7%。

英文摘要:

The existing problems of the linear ultrasonic motor clamping device have been analyized in this paper.A new clamping scheme based on the the doulbe leaf springs has been designed for the V-shape stator with the double amplitude amplifier pole.The double leaf spring structure clamping device can limit the degree of freedom of the stator along the driving direction and accordingly the mechanical properties have been improved significantly,in addition,the two-tier parallel structure was an effective solution to the tortuosity of the stator and accordingly the stability of the motor has been improved significantly.The maximum output force,maximum power and the maximum efficiency of the motor have been up to 17.7 N,0.67 W and 19.7% respectively.
