Mounted dynamic characteristics of washer type piezoelectric six-axis force sensors
To research dynamic characteristics of a washer type piezoelectric six-axis force sensor in a practical measurement
simulation method and calibration method of the mounted dynamic characteristics were presented. According to the working principle and the structural characteristics of the washer type piezoelectric six-axis force sensor
the research methods for mounted dynamic characteristics of the sensor were analyzed. Then
in accordance with experiment prototype parameters of the pre-stressed washer type piezoelectric six-axis force sensor
its numerical model was established
and the numerical simulation method and mounted dynamic characteristics were investigated. Finally
the dynamic calibration method for mounted resonance frequency of the sensor was developed. Experimental results indicate that the mounted resonance frequency of washer type piezoelectric six-axis force sensor is more than 3.9 kHz
and the results of the numerical simulation method are consistent with calibration results. The mounted resonance frequency of the sensor is superior to that of the available technology. The proposed simulation and calibration methods can be used in the prediction and calibration of the mounted resonance frequency of this kinds of sensors.
