The principle of static performance calibration of multi-axis force sensor has been studied, a static performance calibration system for multi-axis force sensor was developed. This system consisted of data acquisition system and static performance analysis system. In the calibration device on the multi-axis force sensor, respectively, imposed load, real-time display information of load pressure on the data acquisition and storage. The data acquisition system collected all-dimensional sensor output synchroly and respectively measurement error of the traditional data acquisition is avoided. Digital filtering and sensor performance analysis module enables real-time online monitoring of multi-axis force sensor for several static index and high-precision calibration of the calibration matrix. Through experimental tests, the calibration system has achieved the desired performance index. It has practical significance for the unity of performance standards for multi-axis force.
