Abstract: The transient characteristic measurement of ultrasonic motor is the condition of its transient control.In this paper,virtual instrument technology was applied to the parameters test of the ultrasonic motor and a linear ultrasonic motor’s transient parameters measurement system was established which based on LabVIEW.The test system was composed of computer,LabVIEW software,data acquisition card,non-contact displacement sensor,and so on.The displacement,velocity and acceleration of linear motor could be measure simultaneously by this system,and the transient response time could also be determined.At last,one linear ultrasonic motor were tested by the system,and the results showed that the test system was credibility and reliability.The test system based on LabVIEW has the characteristics of simple to realize,easy to operate and extend,etc.
