摘　　要：提出了一种直线型驻波超声电机振子,该振子通过改变振子激振频率,利用双面驱动,可以实现双向直线运动。推导出超声电机振子运动的动力学模型的解析式,对振子工作模态和工作频率进行实验分析并对理论分析结果与样机的实验结果进行了比较。A vibrator of a linear ultrasonic motor using standing wave was proposed. The vibrator, by making use of double surface driving and shifting inspiring vibration frequencies, can implement linear movements in two directions. The analytical expression of the vibrator of the ultrasonic motor was deduced. Working mold and working frequency of the vibrator were analyzed by experiment. The comparision in theoretical analyses was made with experimental result of the prototype.
