中文摘要：

根据时空坐标转换理论,对比目前单齿式时栅位移传感器和场式时栅位移传感器有待改善之处,提出一种利用行波超声电机实现匀速运动坐标系的方法。通过对产生行波的数学模型进行分析,可以达到实现匀速运动坐标系的目的。

英文摘要：

According to the theory of space-time coordinate transformation,considering the current defects of single-tooth time grating displacement sensors and field time grating displacement sensors,this paper proposed a traveling wave ultrasonic motor to generate a uniform moving coordinate system.Traveling wave generated by the mathematical model can be used to achieve the purpose of uniform motion frame.
