Calibration method of six-dimensional force sensor

The invention discloses a calibration method of a six-dimensional force sensor. A calibration device of the six-dimensional force sensor is used in the method. The method comprises the following steps of 1) calibration of the calibration device; 2) loading in the Fx direction; 3) loading in the Fy direction; 4) loading in the Fz direction; 5) loading in the Mx direction of the six-dimensional force sensor; 6) loading in the My direction of the six-dimensional force sensor; and 7) loading in the Mz direction of the six-dimensional force sensor. According to the calibration method, different dimensions of the six-dimensional force sensor can be accurately loaded successively, loaded experimental data is analyzed to obtain the static performance index of the sensor, reasons causing errors are analyzed, design the six-dimensional force sensor can be improved via the method, and reference is provided for metering standard and magnitude tracing of the six-dimensional force sensor.
