| Abstract: | The principle and algorithm of measuring displacement in the dynamometer with this accelerometer are presented. Using this algorithm, the zero point of acceleration can be calibrated dynamically, and the boundary value in integration can be determined. All kinds of factors influencing the measuring accuracy of displacement are analyzed quantitatively. An in field experiment result has verified the effectiveness of this measuring method. |
